LGA775 was a legendary platform. I had an E6600 and then got a cherry picked Q6700 sample which was the model above this. I overclocked the bejesus out of them. Good times. Especially when you could buy a super budget pentium E2140 1.6ghz and make it easily run 3.2ghz+ and perform like a chip 5 times its price....
I quickly moved on to LGA1366 and an i7 920 in late 2008 though because that was a genuine leap. It was a best part of 30 percent faster clock for clock than the Core 2 Quads, 8 threads and an integrated DDR3 memory controller with three channels, meaning huge memory bandwidth.
I kept that machine around until last year still doing odd jobs until the X58 board sadly failed. 8 years, tens of thousands of hours of solid running ain't bad for the stress I put it under! I bet that platform and chip holds up a lot better than the Core 2 today because of the aforementioned modern features. I know that if you overclocked the old i7 920 it was still competitive albeit hot and power hungry. Test one at say 3.6ghz and insert the results here please!!
