Just get the 2900

I had the GTS 640MB but sold it because I didn’t find it THAT impressive. If I was buying a card right now and the budget was 250 ish I would not look at GTS.
the thing that really did put me off with GTS was C&C 3, it lagged at high setting but as soon as AA was off everything was running smooth but even 2AA was killing the performance, so I really don’t get all these people here saying that the AA performance of GTS is better than 2900. I don’t have a 2900 yet so I can’t really comment on 2900's AA performance but I know GTS’s AA wasn’t that good.
I played some other games like HL, CS: S etc. and I could run the games perfectly with all the setting on high, but i could get the same performance with 1950 pro i had so what was the point of GTS? Don’t know.
the other thing I didn’t like was the Vista driver, when i switched to vista all the games started to run slower.
atm I’m waiting for the new drivers for 2900 to decide to buy it or not. Hope the drivers are good or I might have to get a GTX.
