ya i'm having issues deciding between the e6750 or the q6600
also with my recommendations:
CPU: e6320 or q6600 or e6750
mobo: p35-ds3r
ram: g-skill nq's
case: coolermaster centurion5
hd: 320gb seagate barracuda
vid card: 8800gts 320mb
cooler: arctic cooling freezer pro 7 or tuniq tower 120 (if u get the q6600, otherwise af7 is fine..... also, if u get an af7, don't buy thermal paste, the af7's thermal pad is good enough)
I really struggled with going for the e6600, q6600, e6420 or the new e6750. I finally made up my mind that I do more gaming than anything and chose the e6750. For $181 I can do some major OCing and in 1-2 years move up to the new quadcores when the gaming industry makes better use of the quadcore technology. That's my way of thinking.
