I tried to set my self up with a GTX260 this weekend, but it didn't work.
Since I get horrible stutters in full screen with any of the new drivers, and because all other games like the new ones, I've had to change back to the 169 driver every time I want to play FSX. I got tired of that so decided to change cards. Well I got the new card at a local shop, took it home, and everything looked good until I fired up Stalker, at which point I lost video, and after that I had tons of artifacts even in 2D. Needless to say I had to return the card and I'm still with my 8800. I think I'll order one for next weekend and hopefully I'll have better luck, and I think I'll ge the version with 216 cores.
