A 4.4 Ghz I7 980 might manage, but I was checking 3 way SLI GTX 680 benchmarks earlier and it looked far too disappointing on a 3.8 Ghz X58 CPU, and my 24/7 clock is 3.875 Ghz @ stock volts on mine (I hate increased heat output for 24/7 use).

I was just doing loads of research in advance in case GTX 690 prices tumble, but without a current high end SB CPU + X79 system, its really not worth going 3 way SLI. I could still get a 690 and sell the 680 I just got today though.
What is scaling from 1->2 cards for nvidia recently? I can probably just do some more research. I just generally get whatever is best at the time, as for my sig I gave my second 5970 to a friend because scaling was pretty terrible on amd cards at that time, though I've read they've improved since then. And as for my cpu I'll likely be moving to haswell in June/July depending on OC headroom. I would consider IB-E if it materializes and better yet if they solder the ihs properly.

I find rebuilding wc to be a huge pita so I will only be doing it once when I decide on haswell for sure or not, so in the mean time I'll be waiting to figure out the best version of the titan and play the f5 game.
