Thanks. The dual holds back 3D Mark 06, but in 03/01/practically all games except farcry 2 its equivalent to a quad AFAIK. Is that correct or do you get better FPS on the quad? Also on air its unlikely I'd get a quad stable at 4.3 so that's why I went dual, and it was a lot cheaper.

The card runs a bit hot with fan on auto; it self adjusts according to temp and never goes above 72%, max temp gaming is around 83 - 85*C. I have replaced TIM with MX-2 so that may have taken a couple of degrees off stock temps but I did it before I fired it up so I don't know.
