[citation][nom]Crashman[/nom]I believe Nvidia has lower CPU overhead. So, if you're going AMD for the CPU, you'd might be onto something with the Nvidia GPU.[/citation]
I don't know Thomas, that is possible. But this fluctuates by driver maturity. A year ago, I know for a fact SLI had way less CPU overhead. When earlier, back in 2009, Nvidia was behind both single GPU and dual. At one point AMD's driver team made huge CrossFire improvements, in terms of CPU scaling, rendering a ton of my data, dated and useless.
From the cheap seats I have strong suspicions NVidia driver's now have greater thread dependancy, at least for single GPUs. So Pentiums will compete better when paired with Radeon is my hunch. Since there were other factors clouding this belief, I'm now looking into it.
