I have a GA-P55M-UD2, heard the mouse cursor bug is especially bad with Gigabyte boards. I could reflash it, especially since it has a back-up BIOS onboard, but I don't know, everyone else works fine, and I don't want to screw with the BIOS if I don't have to. Maybe I should try it on the weekend.
I have a P55A-UD4P, with an ATI 4890 and I don't have the issue.. Hmm
