What Processor is needed to fully utilize a GTX 570?

I have read that a minimum i7 is needed at 3.8Ghz to utilize SLI GTX570.



But it seems to be a debate on a single GTX570.



I am running a i7 960 @ 4.2Ghz but don't know that in other then Benchmarks, that it really has made a difference in games.|||The Intel I7 1366 socket series processors currently offer the most bandwidth in terms of processing data due to their system bus speeds up to 6400 MT/s

Equivilent AMD QuadCore systems only support processor system bus's up to 5200 MT/s no matter what the clock speed of the processor the I7 1366 socket will always be able to handle more data in one go so the I7 1366 route is the most powerfull without a doubt.



As for overclocking your I7's clock speed by a full 1ghz, bringing you up to 4.2Ghz with 8MB L3.

If that's not compatible there isn't anything else faster unless you fork out £700 or so on an Intel I7 X series.
