A few notes about our setup here:
Most notably, we've shifted from Windows Vista to Windows 7 for testing. Let us know what you think about this in the comments section, but it was pretty clear that Vista was never a favorite, so we're hoping Windows 7 is a more popular environment in which to test. We can confirm that all of the games benchmarked here work in Windows 7. FS X did have occasional hiccups when loading a map, but restarting the app fixed the problem every time.
It should also be noted that the GeForce GTX 285 OCFU Edition cards are clocked too aggressively for an SLI configuration; we had to manually turn the fan speed up in Nvidia's System Tools utility in order to keep them stable through testing. To be fair, we also had trouble with the Radeon HD 4870 X2s in CrossFire on Asus' P6T, where the top card doesn't get enough fresh air due to spacing issues.
All power-saving options were left enabled so that Turbo Boost, EIST, and Cool'n'Quiet would function as intended in a production environment.

lashton so we can assume for gaming the 965BE (or 955 oc) and ATi cards are just as fast as Core i7 and i5 but at a fraction of the priceReply -
Dekasav Only thing I don't like is how you knock Crossfire with 2 HD 4870X2's, since when is it even feasible that 4-way CF would scale as well as 2-way SLI?Reply
But excellent review, overall, I'm actually surprised at how the 965BE did, I thought it'd be behind, where it was actually right in the pack. -
dirtmountain I would have liked to see a 780a or a 980a SLI motherboard used to check the SLI numbers on the P2 965BE. I'm also surprised there's no overclocking numbers in the comparison, is that article still to come out?Reply -
cangelini It's upcoming dirt; Patrick is the one working on it (and our Italian team sent word of its i5 and i7s in excess of 4.2 GHz)Reply -
anonymous x Let us know what you think about this in the comments section, but it was pretty clear that Vista was never a favorite, so we're hoping Windows 7 is a more popular environment in which to test
I like vista, rock solid and stable since I got it years ago. Don't listen to the bashers who never have tried the product. -
lashton You giotta remember vista is design for spoecific hardware and powerfull hardware that can run it, so people with P4 3GHz and vista complain about its speed, vista is OK, i dont like it cause my computer doesm't like it thats fine i get over it and chnage my OSReply -
crash27 So there's no benafit from adding a second 285 to a q9550s or an x4 965 be ??Reply
I get a good performance boost from my second gtx280 with my q9650 @ 4 gz
