So I have been doing some research on a new GPU with my mind on a 7950. I may be upgrading my MB and CPU depending on what ivy league brings. But for now I'm focused on the GPU. After reading http://www.overclock.net/t/1175823/a...d-my-issues/30 I started looking for a bottleneck. Now that thread was filled with alot of name calling and disagreement but they did seem to agree this was more of a crossfire issue than anything. So since I have a current crossfire I decided to go looking.
I decided to test BF3 since its new and the most graphically intense game I play. This was only in Multiplayer since its the only mode that matters. I tested 2 maps, Caspian Border and Firestorm since they were large open maps. I played on the same server for all these tests and did not use vehicles in the hope of keeping such a small sample size as consistent as possible.

I did 2 tests on each plus one test on metro for a more packed environment. And these numbers were fairly consistent. I was stunned by the lack of fps difference and since I'm a noob I really don't know what that means. It looks like the crossfire is a mess though. So if anyone can tell me what this means I will be happy to learn.
