im currently running 2 7950's with fx-8350 in portrait eyefinity and it really look awesome, i gotta ask though if i add another 7950 would i get a significant boost or will it bottleneck eventually?
In the end all CPUs will bottle neck the faster the games get and when you through more and more GPU power at them but even GPUs will bottle neck on certain games either because of drivers or the game is not designed to handle multi GPUs.
