I wanted to get an opinion from actual GTX 780 owners.
I'm building a dual Xeon (Ivy Bridge-EP) based workstation. It's main usage is two-fold; work & gaming. Part of that work is CGI Development, which includes a lot of Maya, RealFlow, ZBrush & Maxwell Rendering. The other part is gaming, but not your typical FPS (Crysis, BF, etc), instead Only RTS gaming like SC2, Diablo, CoH2, C&C, Total War, Civilization, etc.
Over at Blizzard forums I learnt that most Blizzard games tend to favor nVidia cards over AMD.
The CGI aspect doesn't warrant a professional card at this stage so I want to stick to Desktop Card for now.
I've been somewhat struggling between choosing GTX 780, HD 7990, which are both identically priced, and also the shortly releasing R9 290x, who's specs came out yesterday and who's price will most likely be very close to the other two.
I'm trying to choose the best card for around $650 which will max all the above mentioned RTS games & also be ready for the next sequels of each which will be presumably more gpu-hungry; but Also be able to provide solid & strong OpenGL/OpenCL Computational power to the CGI apps.
With Blizzard favoring nVidia and either cards being able to max any of those games - so far I've been leaning towards GTX 780 - but I'm still researching the CGI aspect of the decision.
From what I'm gathering - GK110's OpenGL/OpenCL power seems to be weaker then AMD per some charts & benchmarks floating around. I wonder if you guys have an input on this. Also, if there's someone here who has experience using this card with Maya, RealFlow or ZBrush. None of these applications, unfortunately, use CUDA, they all use OpenGL/OpenCL.
Rendering is 100% CPU only so I'm not concerned about that.
Would appreciate any input regarding this to help me decide.
