i myself own an asus A8n-e and i am well satisified with it. i havent had to mess with the bios o anyhting and it has been workng flawlessly for 2 months.
this is my first time with an asus board, the nforce chipset and socket 939 (my last board was an aopen 754 via) and i really only have 1 complaint. that is that the audio i get when playing some of my games (bf-2 its most noticible) my speaker like to give of static during sound effect. this could just be beacuase my speakers are old but that wouldnt explain why everything else sound perfectly fine.
