Yeah which is why when the big games start appearing from November, the 320mb could be a factor, so id get the 640mb GTS to be on the safe side, plays Dx9/Dx10 games no problems now, where as the 2900 gets crippled in Dx10, or do you want to wait until ATi sort their Dx10 performance out, which no one knows when that will be, so do you want to take a chance on having to play Crysis in Dx9 as they still aint sorted their Dx10 performance by then.
