I see where you would be apprehensive. But IME, gigabyte products OC very well. I have a GA-P35-DS3L with a Q6600 (Acrtic Freezer Pro 7), 4 x 1 GB of g.skill 800, and a 600W PSU @ 3.6ghz, 400 x 9. 1.4V, 1600FSB. Ram is at 1000mhz from 800 stock 5-5-5-15. Only thing I need is a friggin gtx280, to upgrade my 8800gts640.
