Avoid nvidia boards if you want to oc a quad, i had the evga 680ia1 with my current q6600, it was a terrible board for overclocking the quad, too much v droop and the north bridge got to hot, eventually my nort bridge chip on the mobo died. luckily my ram was ok. the 680i was a nice board to overclock for a beginner on my dual e6600 but ive been kinda put of nvidia boards after buyin my current asus p5q deluxe
