I’m about to build a new computer. I’m going to go ahead and build it on a Core i7-3770K with 32 gigs of RAM, I’ll be pushing the system up to 4.2GHZ, which, on this benchmark chart, http://www.cpubenchmark.net/high_end_cpus.html , will put it at about 11500 or on par with a Xeon E5-2650.
I’m having trouble figuring out what I want to do with the graphics cards. I have all of the Autodesk student software, but I’m primarily a Blender 3D user. Blender 3D’s new internal renderer doesn’t support OpenCL rendering on AMD cards, but AMD gaming cards are far superior to the latest generation of Nvidia gaming cards for GPGPU work.
Looking at video cards, I have the option between doing something like grabbing two GTX 580s off of ebay, each with 1536MB of RAM, or one Radeon 7970 now and another one down the road. Each 7970 has 3 gigs of RAM on it, which means it can handle more complex scenes while rendering. However, I’d not get acceleration with Blender 3D’s internal renderer.
This isn’t too bothersome to me - I’m more worried that programs outside of Blender 3D will not support acceleration with the AMD cards.
How widespread is OpenCL adoption in other programs? Would I be getting more than I lost if I went with AMD cards?
