I've never (can't) run mine in my Sli rig, but then I don't run three cards either. However I think it would be more of an i7's scaling ability rather than the Wolfdale's that you may have been reading about, I could be wrong though.
depends... i would love to run a heavily overclocked wolfdale with tri sli. you should try it and post some benchmarks!

very well could be the case. other than that some games just scale horribly when you SLI or crossfire. im assuming you are playing demanding games that can actually handle it though...

I think it will perform better, after all, you will be adding two more cores, even if the clockspeeds aren't as high. I am assuming you overclock your chips as well....
3 way 260's is a very powerful setup, and while i have not doubt that a quad core socket 775 will improve over the e8500, an i7 would be needed to unleash its full potential.
