one of the major points for more VRAM i must make is that if no 4GB card ever comes to market then no software would ever use 4GB of VRAM. the hardware must come first.
I mean in the most popular game engines for PC there's no setting for the engine that explicitly tells it how much VRAM to use. Bumping up AA / AF levels is more likely to be core dependent if you have 1 gb.
