Hey guys. First time poster here.

I'm building moving over from a Mac to the "PC Master Race" and building a new desktop to start working with Octane Render for Cinema 4D. I want it to be good for other kinds of tasks so I'm going with an i7-6900K and I am in doubt about the GPUs. Should I go for i7-6900K and 4x GTX 1080s or i7-6950X an 4x GTX 980TI? From what I know there is no support yet for the Pascal cards but I am guessing it will be added soon since Nvidia already released Cuda 8.0 SDK? Is there any benefit to buying the older generation cards (980Ti) instead of buying the 1080s? How much longer should it take for there to be full support? I don't mind waiting a few weeks/couple of months. My build will only be completed in the end of September anyway, and I won't be upgrading it for some years. I also thought about 2x Titan X Pascal but I would get more CUDA cores from the 4x 1080s or 4x 980Tis anyway. The VRAM is tempting but I'm positive I will be fine with the 8GB from the 1080s for now.

Thanks

hi there!

Pascal cards are supported, just build is not fully optimised. One Guy recently made hacked test in OctaneBench - 1080s scored 140, meaning they are on par so far with watercooled (hybrid cooler equiped 980Ti/TitnaXs).

If 12GB is not what You need, 980Ti might be tempting only if You can manage to find them very cheap, but otherwise 1080s would draw slightly less power, produce less noise & cost less giving You 8GB instead of 6..

as for CPU, OctaneRender so far can not benefit from anythign more than 4 cores..- but faster is better, so OCed quad or Six core if You would like to work in the background is more than enought.

as for system drive - as it's already year '16 - lookf NVMe - from single drive You'll get 1500writes 2500reads for reasonable price. & RAM - jsut take good value options as You will not notice any difference even from twice more expensive unit =)

don't skimp on good PSU & case with good ventilations as keeping cards cool matter if You do not want to encounter thermal throotling & start loosing performance =) apart from that it's actually not so much to advice.

feel free to drop some questions if You still have some - Guys on this forum will be happy to help You out & guide to right direction based on their experience.
