I'm looking to upgrade from my radeon hd 4890 so I can play upcoming titles without turning down too many settings. I really don't have a brand preference, but 6950s on newegg include a free copy of Deus Ex 3, which I'd really like to take advantage of. My main question is whether to get a 6950 with 1gb or 2gb of memory. Something like this card vs this card.
