Without sounding too controversial but I think those "mocking" 2GB of RAM on a card of at least GTX 285 should read into things before speaking.
Grand Theft Auto IV benefits from 1GB+ of VRAM and those who are lucky enough to have 1.7GB+ of VRAM (true VRAM not 4870X2 2GB) can play the game with maximum view distance.
ASUS' GTX 295 4GB is a well thought out product, just a shame it is soo late into the game and going to be hideously expensive.
How long is it until the 2GB GTX 3xx cards come out?
