Hey justapost just about to reinstall windows myself again, seems that after a bit of overclocking and testing windows freezes just after boot.(can usually hear the xfi complain) Asus should supply a free xp pro corporate with this board, give overclocking @ 667 a try seems slightly better on my setup. Yes where i live temps are very high in summer so i have noticed the nb temps are very hot, but the board remains stable.
