680i is an ok'ish board if you get a good one it,ll clock a duel core cpu ok, but that usually involves high v core, as for the intel quads theye a bit rubbish, on a 680i currenty running an e6600 on the evga version of this board,@3.6ghz 1.525 v which is quite heavy voltage wise, if you dont need sli look perhaps at the newer intel x38/48 chipset boardsl
