Older test.
I know his CPU isn't the greatest, AMD 1100T overclocked some.
But other than that, I can't really see why this isn't believable.
Edit: Single 460 overclocked resulted in 1903 in Kmark.
So my summary of my sli setup = useless is accurate LOL
single card: 1903
two card with one on physx: 2224
SLI: 1794
