I've got a Q6600 - and let me tell you, it's rugged.
I had something go wrong with my last PC in which the Core 2 Quad was installed. Thinking the motherboard at itself (based on the fact that the mobo was overheating when it died), I bought a new one. It's beautiful; nForce 790i chipset, three PCIe 2.0 x16, and a 2000MHz DDR3 memory standard.
So I haven't been able to figure out just yet how to get the new case's power button to talk to the motherboard. Everything appears to be connected right, but I apparently am green-green colorblind. Whatever, I just wanted to make sure that the power was OK. There's a power button directly on the motherboard (handy!) so I pushed it. It came on.
Sadly it looks like it's my video card that's the problem :(
Anyway, go into the BIOS, look through settings. Pretty awesome for overclocking. Go into the system status window....
I must not have my heat sink seated correctly. Current CPU temperature: 102 C.
Hard power off!
Damnit....
That's pretty intense...
Fuck heatsinks, just boil a pot of water with that cpu.
102c? Sounds like my video cards playing Crysis on Very High. :D
Yeah, something isn't right there. I'd give you some lame noob advice about reseating it, but I'm sure you know what you're doing. :)
Only slightly slower clockspeed and vastly more cache, I am happy with: Xeon E5410 (http://www.newegg.com/Product/Product.aspx?Item=N82E16819117149)'s. (slightly more expensive (http://www.newegg.com/Product/Product.aspx?Item=N82E16819115017)).
Probably for a different purpose than what you're going to be using that Core 2 Quad for, though :)
