That's a nice score for a pair of 480's
Here's mine 580 slihttp://3dmark.com/3dm11/3542517
I'm really let down by the cpu tho
I really got bad luck with this one needs lots of juice to be stable so i cant oc it very high, complete reverse of my last chip a Q6600 which was hitting 4.8ghz stable on a smaller wc kit then i have now.
Tax time soon new chip i think.
Shame about your card lucky it still works in sli tho
I'm running one card on the 8x slot for cooling, i didnt see much difference when running 16x except for a lot more heat.
I still haven't seen any benches that throw any real weight to 16x speed on sli either.
