I've got the twin frozr2 version of the 6870 and it's really good. I'm seeing idle temps around 45C with ambient temps around 65F. I never see any issues in game with stuff maxed out and the card really under load, so +1 for the frozr 2. As was the case a while back the 2gb really kicks in on high resolution, but I know you like to really push the quality settings on your games, so the 2gb can't hurt
also it's only $40 more (including MIR's which are a PITA) than a 1gb with stock cooling, so I say jump on it.
