I have a NF2 based motherboard (A7N8X) and have had a mixed experience with it; it is fast and stable (as far as games go), but buggy. There was an issue where the computer locks up on some hardware/BIOS configurations when restarting the machine through software (i.e. windows start menu, ctrl-alt-del, etc.). I also can't get the SBLive's SB16 emulation to work no matter what I try. Do they have a list of what was changed with this driver revision?
Additionally, I have encountered a problem where the hard drive stops running if the computer is not used for several hours, and I have to restart the machine to get it spinning again; not sure if this is related to the motherboard drivers, but I have turned off the all power management stuff I could find in windows and the BIOS setup program, and it still keeps happening.
