Recently decided to go for 3x Zotac 448's in my system. Went with the Asus P8P67 WS Revolution and sold my old motherboard to break even on motherboard cost. I sold my old PSU and spent $40 more to grab an OCZ 1000W. Here are the results:

I'm pretty happy overall with their performance. The graphics score is closing in on my friend's GTX 680 SLI setup. At stock with his EVGA cards, he hits around 19.2k.

Also, how do you like the performance of those high RPM deltas?
Anyway, I have them configured for use on my Hyper 212+ 1 is mounted as a push through the cooler, then the second one is mounted on the rear of the case exhausting heat right off the backside of the cpu cooler. The CPU see's 60C tops at 4.5GHz. I've never seen the package go above that. In my next case I may honestly load the whole thing up with these fans - they are ridiculously effective.
