why didn't you just post this in your other thread? anyway...
if your going to be keeping that q6700 past 3.6 for everyday use then its a good choice, if not then its a waste of money and get a q6600.
switch the ram to ocz reapers (or ballistix tracers)
you don't need anywhere near that wattage... get a corsair 750tx or a 650tx.
