I think, any card you get is going to be fine for the most part, there are always bugs
associated with any New Product (Not The card, the video game

) ...or the drivers.
So take anything you hear with a grain of salt.
This, coming from a guy ready to spend hundreds on crossfire, and then bought a $100
8800Gt from a BIGBOX.....and I've always felt Ati has "Better Rendering"! WHO Cares!
(ATI fanboy)
Not long after I bought the card, this Cuda, Physics thing came along. I couldn't be happier, No issues anywhere. Runs great! Better performance than when I bought it.
Then again, I game at 1280x1024

, on a Samy 793DF.
