My 580s are bottle-necked at 4.7ghz.

The higher you want to go, the more CPU you need.
Its sad, but do you think the drivers will improve for 3-4 way SLI? Dident SLI used to scale better then ATI?
Also one point of my rig was to have most powerful single CPU system, I knew there would be a bottleneck. But 4 cards is still the way to go i benchmarks IMO, well it was with 480s hope it is the same with 580s except better!

I believe that I read on Nvidias site that they don't even recommend using 4 way SLI unless in extreme benchmarking. I don't think drivers will improve performance if it's bottlenecked. I mean the drivers can improve performance per card, but if you're bottlenecked, I don't think it will do much for you in terms of scaling.
