If 975 chipset has more ram divider, such as working 1066 divider.... it is very easy to out perforamce 680i. Just FSB450 and DDR2 1130.... damn that is killer 975....but how many 975 can do that XD!!!
If i have time tomorrow i will try like 3.7G, 3.8G. since for those two CPU speed i can do FSB 411 and 422 and DDR2 103x and 105x...hopefully with higher FSB and ram speed, it can easy over 680i.
