Since you plan on overclocking for picking the Abit(?) Make sure you get the 2.0 PCB revision for the NF7-S! That makes it support the 400 MHz FSB chips, like the 3200+.
I got my Abit NF7-S from Monarch because they explicitly stated it'd be v2.0 . Now I don't know about Newegg so I can't tell you.
From what I see on the Nforce2 market, ABit is reigning champ because of this mobo
AN7 it's got the uGuru, and all those wicked cool features in the newer boards, the uGuru is like the CoreCell on MSI boards.
Newegg has the AN7 board, just an fyi.
