@eliasklingen:
Det verkar inte som någon här är riktigt säker precis vad som behöves för ditt bygge. Jag påstår inte heller att jag vet. Nu vet jag dock lite mer efter att ha läst på Octane Readers hemsida. Följande står:
"OctaneRender can run on most CUDA enabled consumer video cards, instead of only on high-end Quadro cards that most other solutions and middleware require, but it is specifically optimized to run on Kepler (GTX 6xx, GTX 7xx, GTX Titan) and Fermi (GTX 4xx, GTX 5xx) GPUs. Kepler GPUs allow a higher texture limit (256 compared to 128 on Fermi) and are more power efficient and silent than Fermi cards. GPUs from the GeForce line are usually higher clocked and render faster than the more expensive Quadro and Tesla GPUs. The GeForce GTX 780 and GTX Titan currently offer the best performance to price ratio, but any recent high end NVIDIA card will offer great rendering performance with Octane.
As Octane does not use the CPU for rendering, an expensive multi-core CPU is not required. However, a fast multi-core CPU will significantly improve the scene loading speed."

Så bästa kort kommer vara ett GTX 780 eller Titan, även om alla Nvidia-kort ska gå bra. Lite förvirrande är det med processorn. Visserligen har du rätt att programmet renderar uteslutande med hjälp av grafikkortet, men vilken betydelse i ditt arbete kommer "scene loading" ha. Detta vet jag inget om.
Jag önskar du kan få goda råd hur datorn ska se ut från personer som just arbetar med 3d-rendering. Själv har jag aldrig gjort det. kollade runt lite på nätet. Finns en intressant sida om hårdvaran för Octane Render här: http://tomglimps.com/value-based-multi-gpu-build-for-octane-r... Där står det bland annat:
"You’ll hardly see any difference in Octane Render performance whether you use 2nd or 5th generation core i7 (or even i5) processors. Our golden rule is to be focused on easy expandability of GPUs.
T: So let’s talk more about them. You bought three 780s, not Titans, neither 980s, why?
S: Shortly speaking – for about half of the price you get similar performance to Titan, but when you watercool them, oh Man, these babies show their true power (45% speed-up compared to 4 of them on air with no extra space for optimal cooling). I’ll talk about some benchmarks later on."
På detta forum diskuterar de också hårdvara för programmet: https://render.otoy.com/forum/viewtopic.php?f=25&t=27162.
På denna sida - http://fullscream.com/what-computer-is-best-for-3d-rendering-... - står det bland annat:
"I have two geforce gtx 770s and the setup is working pretty well. There are probably better GPUs now, but the cuda core number did not change a lot with newer generations. On the octane forums you can find recent benchmarks. Oh, you will need 750w or more power supply for your 2gpu SLI system.
We have a render farm with 14 nodes, but if I had to buy the PC for freelancing, I would probably buy good gaming PC with solid MB with SLI and thunderbolt and add a lot of RAM and that’s it.
An extreme overclocked single CPU machine can work better than expensive entry level dual XEON. Latest Asus MBs allows you to overclock really easy, so take a good and spacious Chieftec case and a nice cooling system."
På den här bloggen - http://www.mediaworkstations.info/tag/best-computer-for-octan... - maxa killen ut med ett NVIDIA Quadro K6000 (sådär 50 tusen kr!) och tre NVIDIA GTX Titan Blacks efter att ha fått tips just för programmet Octane Reader.
Jag har kanske inte gjort dig klokare men kanske försiktigare och det är ju bra
