The 7900GS eats CSS for breakfast. That's how smooth it will be. Just another walk in the park. CSS is not a very demanding game. I would say it's recommended to get a cooler like the Zalman VF900, if you're overclocking. For nvidia cards, it's always preferred, with EVGA. But the current cheapest 7900GS, I believe is PNY. Only $119.99 at the egg.
PNY 7900GS 256MB
That's some great news. I think I'll just stick with the cooler I have, no point in messing with it. Okay so I finally have everything I need! Yay.
(P.S. It only came out to $566, so maybe I should get something extra like a subwoofer or new mouse! )
