I now have both an Asus Rampage II gene, and a P6T. Currently working on my my Rampage. I had an ES version of the W3570, which is equivalent to the i7 965x but unfortunately, it was ES silicon, so only did 3.8ghz stable. With my current i7 950, I can use mostly auto settings, but crank the vcore to 1.3v, and increase cpu pll by a couple of marks. Doing 4.0ghz stable now. Would like to find out other's experience using water cooling with 1st gen i7s, and how much can that help, and how much to buy 2nd hand the equipment?
