pc for 3d purpose

[Sordidus]

Hi everyone

I mostly make 3d character art so i use zbrush, maya, arnold for rendering and sometimes keyshot. Almost always i'm running different programs at the same time. (photoshop, zbrush, maya)

Currently my rig has the following specs http://de.pcpartpicker.com/list/rpbXf8

 

Now it's itching again to buy a new desktop but is it worth it? will i feel the difference?

I've been looking for information on the web and concluded a i7-6700k or 6800k (still not sure if i should go for faster single core speed or 2 extra cores for a bit less speed) or would it be worth waiting for kaby lake chips?

Nowadays maya can use more than 1 core but i don't know to what extend. I'm pretty convinced the 2 extra cores will improve the render speed but does this outweight the single core tasks?

I'll OC my CPU and buy watercooling for it.

 

My current gpu is garbage so a 1070 GTX or 1060 GTX will be enough for me i think haven't rly looked into it so correct me if i'm wrong.

Most renderers i use doesnt use gpu yet so i don't see why i would spent a lot of money on a overkill gpu.

 

RAM i'm definitely going for minimum 32gb, not sure how much difference there is in rams so any advice ram wise is very welcome.

 

Probably going for ssd and hdd again.

 

If you have any suggestions and or advice go ahead and give me your knowledge

 

Much thanks!

Personally, I would say wait for kaby lake, but I still don't think you're going to feel much of a difference since you have the top of the line Haswell CPU.

 

The six core will render faster, and usually there isn't much single core tasks with the programs you use.

 

You should get a faster GPU for sure, even though your renderer doesn't use GPU. The viewports on Maya will be smoother with a faster GPU. Also, more VRAM lets you add higher quality textures without running out of VRAM space.

 

I would hold off, as you would have to buy a new motherboard, CPU, and RAM. The performance gain isn't quite worth it in my opinion, at least for skylake CPUs. Maybe for the 6800K

 

I can tell you between my NAS (14 core, 28 thread 2.2GHz), and my 2500K (4.6GHz), the NAS is much faster in maya, even though single core performance is slower than the 2500K.

 

I'm just a hobbyist on 3D modeling, I don't do it professionally though.

Interestingly there have been some issues with the 10 series and a few of the render engines. Just not as good as expected performance etc. That said, the gpu issues that I'm aware of are being slowly fixed.
More Vram here is always shiny as you're probs aware.
GPU will likely be faster than CPU assuming you're using an engine with support and aren't doing anything like hair SSS, or volumetrics.
As to cores - yeah, the more there the better. Some viewport operations may not be multi-threaded but actual rendering should almost always benefit from more cores.
RAM - just get whatever speed you like. Evidently its not a thing to be concerned about.

If you want to get the PC built soon, you could go for the X99 platform. The 5820k offers great overclocking capabilities and it's a 6 core 12 thread CPU. You could also choose the 5930k which is again a 6 core 12 thread CPU, however for the extra cost over the 5820k, it's not worth it, considering it's core clock speed is only 0.2GHz faster. I've had both of these CPUs and have been able to overclock them on the following system

Motherboard : MSI X99A Gaming 7
RAM :  32GB Corsair Vengeance LPX DDR4 (4 x 8GB)
Cooler : Fractal Design Kelvin S36 AIO
GPU : MSI Geforce GTX 980Ti Gaming 6G

I managed to get both CPUs to 4.5GHz and have it be stable and temperatures sitting around 35 degrees idle.
However, for the extra cost for the 5930k, it's really not worth it. RAM speeds aren't really that important, definitely go for at least 32gb for 3D modelling. 

You could go for an older CPU and motherboard choice and get 2650 which are quite cheap on Amazon and they're 8 core 16 thread CPUs. However you may have an issue with finding a board, but the motherboards have support for 2 CPUs, so you could make yourself a cheap 16 core 32 thread system which, because of the core count being higher, would yield better results in 3D modelling

Allright that's some interesting information right here. I think i'll wait a bit longer for kaby lake or maybe check out a build with 2 cheaper 8 core xeon's but im a bit scared of the slow single core speed and if most things i use will benefit from 16 cores. (i know rendering will benefit but i don't want my programs to run more laggy due to the lower single core speed).

RAM now i'm sure the speed doesnt matter that much.

As for the gpu i need to look for more information about the different onces but now i'm convinced i need to upgrade that one

 

@scottyseng so more cores will improve the general speed of maya, like viewport, rendering, simulations? or just rendering?

 

Thanks everyone for the information!
