A while back I built my CPU with 1 Radeon 7950 and a couple months ago I purchased another Radeon 7950. However, I only notice a minimal improvement. Is it possible that my i7-2600 is a bottlekneck? The rest of my system specs are on my account page.
Yeah, in CCC. I'm not sure, I guess I was hoping for a 35%+ improvement. The only improvement that I have seen right not is in synthetic benchmarks. All the games, Skyrim, Planet Side 2, Deus Ex, Crysis 2, etc maybe increase by 2% FPS, while Skyrim actually degrades in preformance.
I would check the load on the GPU's with something like MSI afterburner. Skyrim has issues with enabling Crossfire correct. It took quite a bit of messing around with it to get it to work right with my 6850's. I think I used another games Crossfire profile to get mine to work correctly.
Yes, to be honest, a lot of games actually benefit from just using a single GPU. xfire is tempermental, at best. I'd suggest selling the 7950s and investing in a single 7970.
A lot of games don't support multiGPU on the AMD side right now how ever crysis 2 should be one of the ones that does support it. What I am saying is that a lot of games you will see a very minimal to no difference in performance.
