The GT300/Fermi Thread - Part 2!

[annihilat0r]

what i wonder about is that the cpu requirements for dual gpu setups are not double of what a single gpu setup requires. how come?
its definately higher, but not double, at least not in most scenarios... does anybody know why?

Why should it be double? If with say, a 5870 the CPU was a bottleneck, then it would require double power when you add a second 5870. In this age of console games 5870 can be bottlenecked by the CPU quite often, I accept that but when you're bound by the CPU you are at 100 FPS levels so you wouldn't plug in a second card anyway.

As long as the limiting factor is the graphics card I don't think a second card would require double CPU power.

mhhh good point, cpu limitation shows slowly, first your only losing 1% of performance then more and more the slower the cpu is compared to the gpu...
