Fine review on a very exiting card.

Seems like I may finally move to Vista and Dx10 gaming without spending too much on upgrades.
My only worry with this card is the poor minimum FPS in Crysis in DX10 1680 and above with aa. The GTX280 kills it there.
Is this likely a driver issue? or is it related to not having enough GPU memory? It blasts the other games. I'm worried, though, that some of the better future games are going to be very intensive like Crysis. Alternatively it could the bad coding in crysis. Just wondering.
