I love my 3 7970s, which is why I'm in no hurry to sell them. I've got a target value I'm looking to get for them, and if it isn't reached, I'll be doing a little watercooling adventure with them in my Sandy Bridge 1155 rig.
What it comes down to is, when you're going 4 way crossfire or SLI... if you aren't watercooling right off the bat, the heat is really your worst enemy. Considering that I'll be keeping the 680s air cooled for the forseeable future, they seem like the best fit since they run on less power, thus less heat (even though they run a little hotter which is due to the fan curve).
Another thing as another user pointed out is, as much as I hate to admit it, AMD's drivers haven't exactly been a blessing for me since I made the move to AMD. With single cards it's just fine... but when you start talking Tri-Fire+ you can expect a few hangups, and to be honest I'm just to the point where I'd rather just PLAY the games rather than spend time tweaking issues. Don't get me wrong, there are and will be issues with the 680s as well, but it just seems Nvidia's QC with their drivers is in another league compared to AMD.
With that said, I have MUCH respect for what AMD was able to do with the 7970. For them to be on the back foot with Bulldozer, and fighting a losing battle with the 6970, to pull out a victory like they did with the 7970 (which still overclocks a bit better and performs a bit better when both the 680/7970 are overclocked), is absolutely an accomplishment that I'm more than proud of them for.
I hope AMD continues to trade punches with Nvidia, because if it ever becomes too one-sided, we're in for some stunted progress and price gouges for sure
EDIT: Oh and, there's just that feeling I love from having new tech on the way in the mail that I get to play with that drives me to continually upgrade and ride the silicon wave
