Hello, Stimp3D 🙂

In general, you may take the maximum configuration that allows your budget allocated for this purchase.

More specifically, the:

For the smooth rotation of 3d scene in the viewport the graphics card (GPU) is responsible.The more performance of its graphics accelerator, the more smoothly your job will be to in the scene. In fact, the performance of graphics accelerator is responsible for the comfort of 3d artist in creating scene.

For the rendering speed the central processor (CPU) of computer is responsible. The more its clock speed, the more cores it has, the faster it will compute images.

For that how big scene can be loaded and calculated, the operative memory (RAM) responds. Indirectly, it also affects the speed of rendering. The fact that many modern renderers have special algorithms, which are fighting with lack of memory. In particular, they do not allow you to load the whole scene entirely, and in the process of rendering, it partially load only those parts over which the calculations are made at this time. The less RAM, the lower portions of the scene can be used and the greater the number of loads of these portions will be required to render the entire scene. Unloading process (cleanup) for the new portion and further new loading actually take time and computational resources of the entire system. Therefore, a sufficient amount of RAM will not speed up the rendering process, but it will not let it slow down 🙂
The remaining components such as motherboard, hard disk drives and other, are less important than these three.

For comfortable work with the majority of typical scenes, it will be enough video card NVIDIA GeForce 8800 class. Higher is better and but more expensive 🙂

If you choose a new processor, nowadays the best choice for price / performance ratio, is a processor AMD Phenom II X6 1100T. At a price of 250 USD, this six-core processor are much efficient relative to similar to the cost dual-core 🙂 Intel Core i5-660.

The 8 gigabytes of RAM is enough for almost any purpose.

If the scene takes off with messages such as: UNHANDLED EXCEPTION: Memory allocation failure or The application has run out of memory and will now close. That is no doubt the matter is in the lack of RAM. There are several solutions to this problem. The easiest way to save RAM on the scene geometry. To do this, make a copy of the scene. Select all of its objects. Click the right mouse button in the viewport. From the pop-up menu, select V-ray mesh export. You will see a dialog box. All leave the default, only tick Automatically create proxies. After that, all your scene indiscriminately turn into VRayProxy. Render. A more sophisticated version - is to save memory on the VRay frame buffer. To do this, go to the tab of the window V-ray Render Scene, open the roll V-ray: Frame buffer. It disables the checkbox Render to memory frame buffer. Then move on Common tab and scroll Common parameters The section Render Output PUSH button Files. Choose the format in which you want to render your visualization retained. Render. After that, the specified path in the Render Output 3ds Max saves your render. Of course, without a frame buffer you will not see the rendering process. Alternatively, you can combine both methods to the proxy and the frame buffer 🙂 Last, the surest way - buy 8 gigabytes of RAM😁

In principle, it is normal configuration for their sum, we can say back to back 🙂 The main thing mind you, that you are not a system administrator skills and experience in the server technologies, is unlikely to be able to build and run the system on their own. And the one who you acquire this workstation, a server, take with you from 100 to 500 USD for it. In particular, the new motherboard just to work with processors Xeon 55xx series can not. In order to get it to see these percents have to update the firmware, pre-inserted into the motherboard earlier processor socket LGA1366. And if you dare to put a hot swap hard disk, you will need to sew and his otherwise motherboard will "curse". Also consider that you may need to install a server OC to complete the work of two processors. It's not obligatory. The information on this board is written that Certified for Windows Vista, nevertheless stands Obra% D1 a booster attention. The only thing that is not clear what caused the choice in general, nothing special introducing in the work of professional NVIDIA Quadro graphics cards in 4000 cost approximately 1000 USD? If you start talking about the speed of working directly in the viewport 3d programs or desktops 2d applications, it will not avoid playing the same video card, or even less than half the price category. Benefits NVIDIA Quadro family of graphics cards are very specific: This is a great amount of video memory, compared with game counterparts on the same chip. Actually when GPU rendering. The ability to demonstrate klozap textures greater resolution than 1024 pixels. To do this, put your specific video driver viewport. Availability of Stereo outputs for stereo monitors or stereo glasses. Supporting NVIDIA 3D Vision technology. It is unlikely that you will use at least one of these advantages to the full 🙂 Mountainto rational purchase still playing the video card, such as GTX 560 Ti, which today is optimal in terms of price / quality. And the difference in price is 1000 - 200 = 800 USD, just install the processor with a higher clock frequency.

No 🙂 course, a difference of only one processor. That is, approximately + 120 watts, compared with a single-processor system and a few watts to a voracious server memory. But the situation with overclocking - without options. On the server motherboards and Xeon processors is by definition impossible. Home path server technology is stability. That is why the developers of these technologies have taken all measures to prevent any destructive factors that make deviations from the nominal mode of operation of these systems. The only exception is the specific platform, such as the Skulltrail , based on the Intel D5400XS motherboard, designed for two special Core 2 Extreme QX9775, is essentially a Xeon'ami with an unlocked multiplier. But, firstly, it is very expensive, and secondly has the Socket 771 and is not compatible with modern six-core Xeon X56xx by LGA1366.

Regarding the "big professional monitor and a high-precision mouse," that we ourselves use multihead systems , it is the most efficient solution to fit all the necessary panels professional programs are not doing the opening and closing of the same window. For example, the material editor or settings renderara in the same 3ds Max.No, for the student it will monitor perebor.Esli talk about professionalism, and the only major difference from other - good TFT matrix. Matrix * VA and IPS are the best in terms of color reproduction and a depth of black. Most is for imaging😉 Their price is on average 500-600 USD , not most "student", but it is well worth professional monitors kachestva.Pod high precision mouse, we mean manipulators with high resolution (at 1000-3500 dpi sensor) scanning poverhnosti.Takaya mouse really allow precision control the cursor. If you moved it to 1 mm, and then it will move mm, if you want to get into what that little detail on the screen, you're sure you will get it. The cursor does not jump across it due to the low discreteness movement. There are no jerks and "step" when moving the cursor. It moves really smoothly, plus there is no need to fidget hand across the table to move the cursor from one end to another. Sensitive high-precision mouse will do this with a small displacement of its We tried a lot of mice on a completely different manufacturers and eventually settled on Razer This is really a quality arm, it is convenient, accurate and reliable, but in order to use its full potential, need to be sure to buy a a suitable mat . we ourselves use Razer Mantis Control . However, we believe that any other mat this level would be a good choice😉

Hello, Kuro.I yes and no🙂 On the one hand, yes, color calibration, the first thing that will be performed on a professional monitor, in contrast to the consumer. On the other hand, the hardware calibration is not necessary. It is rather formal, since most printers, namely printing need perfect color rendition, it is usually not used. They do not even use the software utilities included with the monitor and control its zhelezom.Est as is. Most, if not all printers are commonplace Adobe Gamma, in general, has no relation to the hardware directly monitora.Malo particular model, they use different profiles for its different events and programs. They do it all the time and switching the settings on the monitor itself would have gone crazy🙂 Even hardware calibrators, and are not related to the hardware monitor. They are set up with, put the driver, who, on the basis of data from the sensor colorimeter or spectrophotometer, operate Windows Gamma. To be more precise, they re-adjust the color lookup table CLUT (color look-up table) video. In general, far ushli.Tak here, it is a color calibration, most important printers to adapt to the specific printing press and a specific paper with paints in order to receive a printed print the same way they see it on the layout monitore.Nam same with you, trideshnikam I mean, it is not very important in getting the perfect palette sluggish CMYK printing devices. Most generally not important. We contrast is important, "liveliness" and the brightness of colors. The black color on the monitor should be primarily black, not greyish, because of the peculiarities of the implementation of domestic lighting TN matrix monitor. The picture on it should not be explicitly "the monitor", burns the eyes, it must be, above all, soft, because it sometimes, you have to peer chasami.Eti characteristics have no relation to the LUT hardware calibration monitora.Dorogaya matrix rather simply defines device class. After all, in fact, e-filling, that in the domestic monitor that professionally - is the same. Only a matrix raznye.Skolko you do not torture TN + film, no matter how much the caliber of its gamma settings, profiles, or even a hardware calibrator, it still does not give a good picture, simply because it can not in principle. At the same time, such as monitors * VA or IPS matrices, even "out of the box" immediately provide excellent pretty picture, without calibration, better than domestic monitore.Ty easily distinguished even calibrated IPS matrix from TN + film, what would it not setting proizvodilis.Po about bit depth, we completely agree that the higher it is, the softer / smoother gradients transmitted monitor. However, it is still not an indication or a mandatory attribute of a "professional" .There is very popular among professionals monitor Dell 2407WFP: at the time, he was worth in the region of 1000 USD. There is no doubt that it is about Monica, but the fact is, its color only 6 bit. But at one time it did not bother professionals. Professional monitors with color is below 10 bit - polno.Vozvraschayas to the advisability of purchasing the monitor for about 600 USD, except for the above soft picture and just its subjective quality, we can not ignore the fact that domestic monitors are not intended for long hours peering into pixels on them. They need to play in a toy, a film look, but it does not sit in front of them for 8 - 12 chasov.Bytovoy monitor their excessive variegation backlight brightness - "burns out" eyes. On it just uncomfortable to watch. At least if you compare it with the PRO Monitor. Suffice it to move away from its pro or semi-pro monitor and sit at home, how do you just start to get tired and watery eyes. If you all my life sitting before the household, then your eyes a little accustomed to the brightness is not so sharply react to it, but they were still much faster tire compared to the eyes of the one who sits at a professional monitor, specifically designed for long hours of work before nim.Tak why buy a professional monitor for $ 600 if you're not doing the graphic arts industry and, accordingly, the calibration is not very important? Then it would be just more comfortable working for a long time after him, nicer to look at him. As we said earlier, for constant work with images on the computer, we believe 600 USD spending to a comfortable eye monitor - the primary and justified waste, and familiarity with the characteristics of the ophthalmic industry - the last thing, even if it is cheaper😁Otlichnuyu visualization can be done and monitor the cheapest. It just about caring for your comfort, like instant - to see a beautiful picture, and on the perspective - eye health.

Yes, Lachesis also breaks down after a few years of use - starts to run over and sink the button. In DeathAdder for 5+ years, this was not observed. But, apart from this bug, of Lachesis is positioned like a mouse for both hands, and, unfortunately, the result is not very comfortable for either of them 🙄

Hello!

Well done, that you think about the right things😁

Additional systems for rendering are a great solution. Immediately make a reservation, we will not discuss the creation of a cluster, as such, because This technology goes far beyond the "household needs" of rendering scenes in 3ds Max and V-Ray. As you know, V-Ray has its own technology of network (distribution) rendering. Let's make it clearer (maybe someone who does not know), determine what kind of computer that does with network rendering V-Ray.

The main computer (Render Client) is the computer on which the main rendering process is started and maintained. That is, in your case, this is your current PC on the Core i7 930.

Render Server is an auxiliary computer connected to the master on the local network. It takes data from the main, processes them and returns them back, thus speeding up the rendering of the image. That is, in your case, this is the additional computer that you want to buy.

Theoretically, it is desirable that all computers involved in network rendering be identical in performance. However, as practice shows, if the host computer is faster than the render node, then it will not be worse than in the case of an identical server and client.

In addition, as we have already mentioned, in the case of rendering scenes using Light Cache, which is not distributed in distributive rendering, but rendered on all network computers in parallel, it makes sense that the main one was the most powerful computer on the network. Then it faster than the nodes will calculate the light cache and, thereby, reduce the total rendering time.

Therefore, for the server, you can choose exactly the same, you have now, or less powerful processor.

The next thing you should pay attention to is the amount of RAM. It should be understood that in network rendering, the scene is loaded not only on the client, but also on the servers. And it's rendered similar to them. Therefore, if, for example, you have 12 GB of RAM on the host computer, 4 GB on the node, and the scene needs 9 GB of RAM, then after starting the network render, the scene will start rendering on the main one. But, at the same time, on the node it just flies with the vray memory allocation failure because of the banal memory shortage.
You need to understand that on the server you will be able to render only those scenes for which there will be enough RAM installed on it.

The last thing I want to say on the theory of the choice of hardware for network rendering is that on the server the scene is launched in the background and it does not matter which video card is installed on it. It is simply not used at all. The other components are even less important.

Here is the recommended configuration for rendering: the best computer for 3ds Max price / quality. At prices of the end of 2011, for 400 USD you can collect an excellent render-node on a 6-nuclear phenomenon with 8 gigs of RAM, without taking into account the price of the hard drive. Winchester in the account does not take, because of its current mixed price.

For example, we, for nodes, use just such systems. They have motherboards with integrated graphics cards. This is convenient, cost-effective and does not affect the network rendering speed in any way 🙂

If you have more than one entry into the monitor, then, as a rule, in the menu of the monitor should be a function of switching the signal source. In some there is even a separate button for switching. With these problems should not be at all 🙂 If this button / menu inconvenient, you can use remote control computer program, for example of Radmin , with which you can easily manage additional computers from the home. First amdeshnye eight-FX (and you gave a link right on this one) have meager growth performance compared to top-end Phenom II, and in some cases they are even worse. And if we consider that for rendering with V-Ray number of threads, as such, does not gain performance bottlenecks etc, that make sense to pay extra for a formal no novelty 🙄

It is noteworthy that during the use of render nodes, as if everything is fine however, occasionally need to use a monitor, keyboard and mouse directly, not to mention the initial installation of the operating system, drivers, and the same radmin. Therefore, if you can not use both the signal on one monitor, then at least take care of the fact that this computer was somewhere nearby 🙂

Andrew, to processors apply the same principle of choice. The number of threads is usually equal to the number of cores, Hyper Threading when using the number of threads can be increased technology. On the contrary - it is impossible😁 The main thing here to understand what is important to render only the ultimate performance, regardless of the number of cores and threads. Aliens recommendations we do not see, so I ignore them and just say that you should see the tests in multitasking applications of interest to you processor, and then look at their price and understand you better. Either the reasonable price with high performance or slightly higher performance with a high price 🙄

26 Mar, 2012 # Re: Useful Info on getting PC for 3d (quotes)
Setting up a distribution network for rendering with V-Ray is no different from setting a home or office network, it just has to work 🙂 If you are a regular user, the only advice here is to buy a switch and stick to it all the available computers, even if only two of them. This network diagram works immediately, without setting up, without which it can not do in the case of connecting two computers directly to the network cable. The more important question is the organization of the network share to the texture to be "seen" by the identical way on all computers. But here there are no special tricks. You just need to connect the network drive, as is done in all other cases. With regards to the other questions, please see the previous posts of this discussion.

Hello!

Ilya_sp correctly expressed the basic "postulates" of the choice of render-node, which consist in the fact that this is exactly the same computer to which exactly the same requirements are imposed as for any computer for working in 3ds Max, the only difference being that directly It will not create the scene itself, which means that the video card does not play any role at all, since it does not participate in the rendering process at all.

Considering the above, the video card built into the motherboard is more than enough, since its only "role" is that without it, the operating system😁 is simply not launched, therefore it is formally required as a basic component of the computer.

As for RAM, in principle, on the nodes you can keep less RAM than on the control workstation, because on it you, simultaneously with 3ds Max as a rule, run the same Photoshop or After Effects, which are gluttonous for memory, Than 3ds Max. However, it should not be less than 8 GB, since this is the minimum that is usually enough for most scenes.

For example, I have 32 GB on my workstation and only to use the swap less, and all nodes work with 12 GB. Not once the problems were not with one scene, that is, in my experience, 12 gig more than enough.

Concerning the screw, then on the nodes it is needed solely for loading the OS and there is nothing more for it. Therefore, as bootable disks, you can use the most "killed" and B / Ozny disks of any size and speed. We do exactly this, saving the component in the nodes as much as possible😉

In today's market, most, if not all, 27-inch monitors begin with the permission of 2540x1440, which gives this diagonal high enough pixel density: worry about more pixels is not necessary. As for the cover of the monitor glossy or matte, it is more a subjective parameter. Yet glossy looks very attractive in dark rooms, and matte - the only thing that is suitable for bright rooms. For example, I do not recognize the urgent need to work to have a very bright and contrasting colors, my personal choice - a universal matte screen with a "quiet" colors. Choose eye😉

Rostislav, I would not be so committed monitors Dell brand. This is a cool company, but its shortcomings in her too. Be sure to pay attention to the fact that, with similar marketing labeling, the Dell monitors may have different specifications. Model U2515H too small diagonally and has a very high density of pixels, all models S2715H, P2714H, SE2716H have too low resolution 1920x1080.

In your case, I suggest you look for these key models, and possibly their "neighbors" on the series of the same brand. Below is a list of monitors arranged in ascending order of price, the main characteristics of all - very high and most importantly, similar. All of these monitors are the best value.

  1. BenQ GW2765HT from 375 USD
  2. Dell U2715H from 490 USD

Therefore, the assembly on the 4170 processor, is already outdated, it would be the worst option. In addition, the video chip from i3-4170 basically enough for comfortable work in 3D.

gus_ann, hello! Regarding iron I will look in more detail, but once I can say that the renderer that is configured to work with a large amount of memory on a PC with low volume, simply does not "bloat" 🙄 This will work only PC-monster, and PC -dohlyak or throw an error, or stupidly hangs. We need to clearly define the purpose. Then form a solution. Then choose Circuits on this decision. I propose to start with the first: let's clarify the situation😉


27 Jan, 2012 Anton (Staff Author)
27 Mar, 2016 # Re: Useful Info on getting PC for 3d (quotes)

Hi gus_ann,

I will express my opinion only on the software part.

Embree is a library of ready-made "commands" or software "kernels" (kernels) specially "honed" for ray tracing calculation using algorithms (SSE, AVX, AVX2, AVX512) of Intel processors. That is, in fact, Embree presents itself as software modules written at a lower level than the programming languages ​​on which the renderers themselves are written, for example, V-Ray is written in C ++. More precise commands for performing certain calculations, especially those associated with the work of specific algorithms of a particular iron, than allows the functionality of C ++ itself, you can not write on it. They are written in low-level languages ​​and connected to high-level modules. These are the modules that directly address specific Intel processor algorithms and are designed to execute commands typical for raytracing and are provided by Intel programmers working closely with the engineers of this company who create the processors themselves. These modules have nothing to do with V-Ray, they can be used by developers of any software, any renderer. Therefore, to assert that a large amount of memory will allow Embree to work at 100%, let's say it is not correct. No direct connection with the memory and use of Embree - no. The only thing that can be attributed here is that nominally Embree, as another algorithm, can use a different amount of memory than the standard V-Ray algorithm, including more. But specific data on whether more memory "eats" Embree than a standard raytracer, I do not have.

The only "summary" of all the above is that Embree, which gives a significant acceleration of rendering, works ONLY on Intel processors. With the tick in the checkbox "Use Embree", the renderer even crashes on the modern AMD processor. Verified!

However, in the presence of a large amount of memory and acceleration of the rendering there is a link. It consists in the ability of V-Ray to work exclusively in the Static mode. That is, the whole scene is loaded entirely into memory, without the need to load it on the "chunks" from the disk in Dynamic mode. The difference between the Static renderer and the rendering of the same scene, but in Dynamic, depends on the scene itself, but at times quite significant. And here comes the question. What will be faster, to render the scene ONE computer with 128 Gb RAM in Static mode or at once DUAL (Distributed Rendering) computers with 16 Gb of RAM in each, but in Dynamic mode. Specific experiments I did not conduct, but something tells me that two computers with a smaller number of memory will cope with the task faster than one, even in Dynamic mode.

Why do I say two against one? Yes, because for the price of only 128 Gb RAM you can buy 2 wonderful render-computers on a good processor, like 4790K, with any motherboard for it, with a built-in video card (the video core, in fact, is built in percent, so all motherboards under It has a video output by default), 64-128 Gb SSD and at least 16 Gb of RAM. Another thing is that you need to have a place to put just two computers and more. Have an infrastructure, that is, supply power, stabilizers, network equipment. But the latter is not at all expensive and not so difficult to configure.

About what is forced on Distributed Rendering to count both computers in different modes, that is, one in Static and one in Dynamic - it is impossible, Max already said. Or both in Static, or both in Dynamic, respectively, have a different amount of RAM on the computers involved in rendering, almost meaningless. Why is it practical, because on the render-comp that is somewhere there and only renders, except for the rendering itself, nothing is started and all the memory is available. At the same time on the working computer from which you launch the renderer for sure and the photoshop is open, and the browser, and skype and marvelous, etc., etc. Of course, they, in turn, "eat" memory leaving less renderer. In this connection, it makes sense on the main working computer, to have a bit more RAM than on the render-computers.

Gus_ann,

Overclocking or overclocking, in simple words, is forcing the processor to work in a more intensive, and in a more productive, mode than the manufacturer's. The manufacturer sets the operating mode of the processor with an orientation to super-stability, reliability and retention of the level of heat release / energy consumption at the declared level.

At the same time, in many processors the manufacturer embeds the uncomplicated overclocking function, knowing that the processor in theory can work in a more intensive mode. But the very practice of overclocking, namely experiments with the level of intensity, it leaves to the user, the enthusiast.

The only, but very fat, overclocking advantage is the increase in processing power of the processor by 5%, 10%, 15%, 20%, and even higher, depending on the luck and perseverance of the specialist. At the same time, for this added power, the processor does not become more expensive in the store 👍 You pay for usual, but you get faster.

Minuses of overclocking can be considered:

    
The waste of time and the need for knowledge of all the nuances of overclocking.
    
Possible instability of work, if the overclocked mode is insufficiently tested by a specialist, which manifests itself in the spontaneous shutdown of the PC. Yes, with a malfunction of all rendered😁
    
The cost of a more reliable motherboard, which is forced to work with the processor in an intensive mode.
    
The cost of a faster RAM, which should "keep pace" with a faster processor.
    
Disproportionately increased electricity consumption. The matter is that with the increase of absolute computing power, the energy consumption goes many times more than when working in a less intensive mode. You can say inadequate. This can have a good effect on the electricity bill, giving a relatively small increase in performance in the same renderer.
    
The cost of a more powerful power supply.
    
The efficiency of modern electronics, and especially, of powerful processors tends to zero. For simplicity of calculations, the amount of electricity expended by electronics is equal to the amount of energy of the by-product of the work of this electronics - heat. Given the pre-previous minus, it also generates this minus - the allocation of excess heat, disproportionate to the increase in productivity. The computer begins to heat up the surrounding space, which in turn can create problems with the comfort of work. If you are not from the cold edges😉
    
The cost of a super-efficient CPU cooling system, which, as we have already seen, begins to work> consume> allocate disproportionately more and, therefore, unnecessary heat energy from the processor needs to be more quickly removed.
    
Increase of noise in the result of the previous minus. Faster cooling is almost always achieved, among other things, by accelerating the air flow through the cooling radiator. The faster the air, the more noise it generates. This worsens the comfort of finding a person next to the PC. Or, at least, does not improve it, as it were, if you put a very good cooling on the processor running in the normal mode.
    
Probably a more voluminous and more expensive enclosure that will accommodate a large efficient cooling system, as well as give freedom in the physical organization of cooling.

But the main disadvantage from calculating success in overclocking the processor is the lack of success. The manufacturer does not vouch for a significant, or even any, performance gain when overclocking this particular sample of the processor, which you got randomly. There may be a situation that you choose and buy a processor, counting on its overclocked power, but it does not deliver this power; Then it can come out that it is less profitable than some other.

Gus_ann,

I, for example, are not inclined to overclocking solely because of considerations of rationality, i.e. Price / quality ratio. Overclocking greatly increases the price for the sake of the growth of absolute productivity. And this is trivial against rationality. As for the costs of increasing the level of related elements, both for costs of disproportionate consumption of energy, and for headache (= costs) for organizing a powerful infrastructure for supplying a large amount of electricity in parallel with the removal of heat.

As far as I understand, your task is somewhat different. Namely, get a powerful PC that will allow as long as possible to not care about the next upgrade. The problems of outlets and excess heat, having only 2 PCs, do not arise. For this purpose, overclocking can be considered justified. Just make sure that the computer is configured carefully, at the highest quality level, with 100% stability. Then everything will be fine and nothing will spontaneously turn off 👍

The very "physics" of the overclocking process has a lot of nuances, with a lot of problems, their derivatives and solutions. The topic is very complex and even many experts do not bother to understand what is actually happening inside the processor. A computer user and even more so this is all you need to know. On the other hand, overclockers understand first of all the practice of overclocking, "feel" the behavior of the processor when it is output to a more intensive mode. Again, the user knowledge of a particular sequence of overclocker actions and to anything, and in principle is poorly understood.

In the most common case, overclocking your computer by a specialist, if the PC is already purchased in the specified configuration, will look like an endless (rather, many hours) clatter of digits in the BIOS, monitoring the temperature on the screen, rebooting, running programs that load the processor and so on, Until it finds an ideal combination of internal parameters, allowing you to have a performance boost with stable PC operation. Something like a typical hacker scene in the movie + swearing😁

taras, I thought you had already bought a PC and plunged into the wonderful world of endless pererenderov 🙂 Intel Core i3-6100 and absolutely and relatively better Pentium G4500, so there is nothing to choose between them.

taras, fine. You simply insert the 4-pin connector from the power supply in the half 8-pin motherboard connector. In what kind of half will not select, as there are clues in the form of pins in extremely desired. It is trite energy-parallel line and the need for more arises in the case of heavy consumption voracious processor. But not so with you.

Lech, hello! Besides the question of trouble-free installation of 3ds Max and other software on the Microsoft Windows Server ™, with whom I have never encountered banal, in principle, no restrictions. Therefore, it is possible. The other issue (s) in rationality. If that server is probably it has its more important tasks? Or is he part svboden and you can bypass the restrictions on rendering time, priority tasks afiiniti cores? If it is possible to "sit" for that server, then this is the best option, because for a complex frame LightCache considered only the main computer. We are talking about multi-frame rendering through Backburner? Then the host PC may be at least a dead laptop, he does nothing renders. In a single-core PC performance better? The one and do the main. And whether it is necessary to do the main render? It's about the available rigah or purchase plans? As you can see, there are so many nuances and must take into account all before deciding if you want it to be the most faithful.

Mila, the performance of a modern top-end iron already begun significantly exceed the workflow needs of 3DS Max. So, please, plan and clarify what are the main objectives and constraints for assembling the chassis. We are talking about a workstation, render-node or 2-in-1? For 3DS Max work station so the PC, and a budget is simply not needed.

shoegazer, if in the first instance take account of rationality, any PC, workstation, render-node or 2-in-1, to be built on the most favorable processor. Unavoidable costs of internal infrastructure, like the motherboard, power supply, memory, etc. limit our choices only the fastest processors: only if it all pays off. Today it is only * CPUs Intel Core i7 series. Rationally advantageous that, fortunately for us, and also very productive, this processor Intel Core i7 from the 3rd to the 6th generation , in addition to X-versions. Therefore, in any case, for the workstation you need to buy any i7 processors, such as the 6700 do not even need to talk about the i3 and to what extent it is not suitable for the job. Regarding incredibly cheap X5570, each of which produces half of the performance of the i7 processors, spending 95W work, I unfortunately do not know anything. Just to say that because of the excessive consumption of a relatively small capacity, each year renders one such processor will "eat away" the excess electricity at USD 25-30, in addition to the usual costly server components. Here it is necessary to calculate in detail, after weighing all the information. Yet, if such assembly would be beneficial, fundamental problems rendering server hardware should not be. * - Only Intel processors have been taken into account in connection with the exclusive support of Embree functionality, significantly accelerating Vray render.
