I recently picked up my mates old i7-960, PT6D Deluxe and Kingston HyperX ti 3x4GB 1600. Took me about 3 days to research on how to OC this chip, coming from LGA775 I was quite noobish although I have OC before. Anyway I found a stable comfortable configuration which was well worth the time taking to tweak and test.

I'm pretty sure I can OC my setup more however I'm waiting to upgrade my case and go watercooling which I'm still doing some research on, because right now I'm using a Prolimatech Megahalem REV.B w/ 1 120mm Scythe Silent Fan @ 1500rpm constant. I used IntelBurn Test for stress test and passed 10/10 cycles on Maximum settings. Max temp I hit was 86c, which seems very high for 24/7 usage. However I read IntelBurn Test is more efficient than Prime as 10 cycles of IntelBurn Test is pretty much equivalent to running Prime over night and that it stresses 20% more give or take.
In conclusion my final OC in real world environment (how I use my PC) never even comes close to 86c. Ambient 22c, Idle 40c, Max 66c which I'm more than happy with considering I'm using air cooling.
Here is a screenshots of my achievement:
