Hmmm... Taking away the buggy Guru, AN7 seems to be a lil bit more 'polished'. Things tend to be more convenient...
The only thing that bugs me is a missing COM2 port - yeah, I know that COMs are obsolete, but I do have a USR Courier and COM IrDA adapter, and don't want to throw any of them away...
Overall, it seems that there's no reason to upgrade from NF7 to AN7. But if you're considering a purchase - AN7 is preferable... Who knows, maybe Abit guys will rewrite the uGuru/BIOS and make it work as supposed?
