Re: I dunno about the 280..
Looks like I'll be skipping this go around. Everything runs well at 2560x1600 with a single 8800GTX here (with Crysis and Bioshock being the exceptions, but even they're playable with a couple of options turned down). So I'll see what AMD has to offer later this week, or wait until the fall/winter refresh (when I'll be upgrading the rest of my system, anyway).
And damn, the power draw on full load...
