I don't disagree with Dylan, but I'm more than willing to bet that the only reason Nvidia's cards (and that's who we're talking about. CUDA is a hell of a moat.) are RAM-starved is that they haven't felt the pressure to do otherwise. AMD has an institutional aversion towards good software. Intel isn't even an also-ran, yet. Apple and their unified memory architecture may be the prod needed to get larger levels of RAM available to single cards solutions. We'll see.
