Speaking for myself, I just have the BIOS set to
FAST with an AGP aperature size of 128mb (which seems to work best for my GF3). Although they make it easy to o/c the FSB, I really don't think there's much to tweak in this BIOS (compared to my old KT7-Raid anyway). I did post
this BIOS tweak for DVD-ROM/CDROMs over at another messageboard, but you may not see any benefits from it since you're running Win2k.
