Don't we already know (or it's rumoured) that AMD's 7600 cards are 8GB?If amd gives you worse for same price then its a different story.
Hope amds counter to this has no less than 12gb vram
It wouldn't be at all out of character for AMD to attack nVidia's lack of VRAM and then do exactly the same (or worse) themselves. I think there must be some kind of feud between their marketing and engineering depts, given how often they say one thing then do the complete opposite.
