yeah I got it cheap too bad the 6th core's defective
That's too bad. They don't make bad quad-core chips though since they overclock about the same as a 955 if you're lucky. Plus they get the turbo core feature like the 650T and 840T, which on some boards you can keep enabled even when overclocked. Handy to get an extra 100MHz boost over your 24/7 OC for single-threaded load apps.
