I found an interesting article regarding this PCI Latency issue here:

Does anyone know if the Abit BH6 is affected by this?? PC is at home, I'm at work, so I can't poke around in my BIOS yet, but I don't think I remember seeing the PCI Latency setting. Does anyone know if ATI's latest drivers fix the problem?? (I mean, gheez! the article is dated June 1998!)

Has anyone had any experiences (good or bad) with TweakBIOS or PowerStrip?? Is there another way??
