It is the KO, so it is already overclocked a litte.
Stress test on CS:S gave me 235 fps, maxed out with 4x AA.
I played Quake Wars, pretty cool game....I love the large maps. Anyways I had that maxed out at 1680x1050 and it looked amazing too.
So far I have to give it an A+. This could be one of the best video card releases ever. I've had a card in every Geforce generation since Geforce 4. I was very happy with my Geforce 4 and Geforce 6 cards, and this tops both of them in terms of satisfaction.
Geforce 5 and Geforce 7 cards didn't impress me much. Neither did the 8600GTS.
