Can't say I've heard much about 2GB versions of the GTX460.
Like mentioned, motherboards will all support both ATI and nVidia cards. The only thing you ever want to check, if you're interested, is crossfire/SLI compatibility.
I think a higher clocked card will perform better than double the memory.
