what do we know so far? i cant seem to find much on this.

975 is a bigger number, so i'd expect it to be the top of the line, but will 965 be good enough to get the same ballpark 3.5-3.9GHz on air out of the E6600? or will it overclock slightly less than the 975?

i've never used intel (well, not since 266MHz days), so i dont know how the upper-lower range chipsets compare.
