A word of warning about the Abit WZ bios update. I flashed my bios from WW to WZ yesterday, and when I went back into the bios to overclock via changing the multiplier from 10x (1 gig tbird) to 12x like I had it on the WW version, my pc froze just as it was entering windows. All I wanted to do is have the ability to unhook my cpu fan from fan header #1 on the mobo, and now I can't overclock. Cut off my nose to spite my face kinda situation. I later read on the Abit KT7 Motherboard FAQ website, that many people have reported having this same problem. Although they claim that WZ seems more stable, I'm flashing back to WW because I want to overclock, screw the fan and the "seemingly more stable" bios. Crap...
