Get the right 3rd party non-reference card (IE: The one of the dual fan cards) and you can overclock it to roughly 670 performance, with quiet fans to boot.
Slightly tempted to get these (two of them), but no...While it has some nice new features and good performance over the 570, I think I'm just going to wait until the 700 series. Let's hope they improve the architecture as much with the next generation, or at least refine the Fermi architecture (more performance & less power consumption/heat). Then I'll splurge and get a whole new rig instead XD
