Well before you buy the NF7 series, I have one warning, and I use this board myself, you don't have precision Vcore control, and the MB undervolts the MB, when I put 2.06 into the bios (and you can't type in a number and the notches aren't equallly assigned) I get 2.00.
Personally I like the MB (I have a NF7-S v2 check my sig) because with the same CPU and same ram and same multi and same voltage, I got one FSB notch higher than my v1 8RDA stable. This was from 168 (2268) to 169 (2281) at 13.5x multi. I replaced my CPU cooler and got it 3 more FSB up. Then I was like this is so close to 14x166 (my dream was to get it to 166x14 and it came true when I switch from a TT Volcano 9 max speed to a TR SK6+ with TT SCF2) so I switched to 14x166. I don't play games so I have no real need for a high FSB plus I have ghetto ram.
