I bought this mobo also, installed windows xp, installed drivers from cd, crashed after sitting on desktop for 30 seconds. tried different ram, video card, disabled onboard sound, no go. tried default settings. no difference. I am using a x3210 quadcore that works perfectly in my other system. I called motherboardpro.com about returning the mobo and was told i wasn't the only one having problems with the new asus mobo, I sent it back, ordered a p5e, sold my 2 8800gt cards, ordered 2 3850 512mb cards. I have tried 3 different nvidia chipset asus mobos, can't get any oc at all, sometimes no default at all, on my quadcore cpu. All this pain in the butt to try and get sli rig up and running. My quad fired up with no probs in the p5e, 3.2 in like 2 minutes. videocards will be here tommorrow. No nvidia for me for a while....if i had not tried 3 times already, i might have the patience to try the evga version...sick of swapping mobo's and installing windows, just to be let down over and over. I only need it to play diablo 2 smoothly anyway....
