I have a Q6600 G0 and an E8400 C0 in stock. Take your pick. Neither one is a golden chip. The E8400 has run a 10.3 second Super PI time when it was on the edge of self destruction at 4.5 GHz. Definitely not Prime stable but lots of fun all the same. It's max Prime stable is down around 4000 MHz to 4050 MHz. I run my Q6600 more conservatively at 3 GHz and I have never pushed it to extreme levels. My old motherboard with the 965 chipset isn't great with Quads so I didn't think there was much point. Either chip is good enough for me so take your pick. Your E6600 is kind of like acquiring a rare fossil. It might provide us with some new information and be the missing link in the evolution of TJMax.

Send me a PM and we can work something out.

Edit: I lied. It actually ran 10.250 in a 1M of SuperPI.
