Originally I was looking to get the 5770. A user commented that the 5770 was the weakest link in my build. I've been looking at benchmarks/reviews for it. It seems like a good card. Anybody actually own one? Care to comment?
Forgot to mention, I switched the case to the Antec 900.
^ Even nicer build
The p6t se is Crossfire capable and the 5770 flies in CF, but even a single card should handle your monitors easily enough, so I'd also suggest one of those is the best way to go.
The 4890 or GTX260 are tempting, but for a new build they have a far shorter life than the new 57XX or 58XX cards. You may come to regret purchasing these faster but 'old and 'obsolete' cards in the not too distant future as DX11 gains ground.
