I ultimately want two cards, that will not cook themselves on long gaming adventures fully overclocked. That is why I worry about stock coolers. I see no DC2 or Twin Frozr 4GB version of the 680/70. The 7970 on the other hand, well lets just say I want to move from ATI. They have been great, I just want to return to the green team.
So what would be my best choice in terms of OC, acoustics, heat, and performance?
Of those choices, for what you're doing ... I would probably get two of the 7970's since they're only $439 after MIR, and that one has a better cooler than the other two ... and 3GB is plenty for 3x1080p. Plus, as others have mentioned, when your resolution gets high, and you start turning on AA ... the 7970 is likely to hold up a bit better due to it's memory bandwidth advantage.
The 680 is a straight rip at $100 more than the comparable 670, so I'd rule that out. The advantage of the 670 over the 7970 is that it's nVidia, basically.
I prefer Forceware to CCC,
I like being able to tweak/make my own game profiles (esp. handy with SLI) via nVinspector,
I like that nV has game profiles built in to the driver AT ALL,
I believe SLI is noticeably smoother gameplay than Xfire,
I like having hardware physX capabilities
I like using SLI AA mode from time to time with older games ...
