no, no, no, no, no !!!! Asus was, used to be good but now it isn't
Ever since they started making socket 939 mobos, they have had failures again and again in bringing out the full potential of the athlon 64s. They had to recall some of their first few mobos because it was plagued with so many problems.
Also, Asus tech support is very awful, they're like indian people with people who can't speak english. So, when you have a problem with the asus mobo, there's a 5% chance you'll get it fixed.
look for yourself in this bench mark.
MSI k8t neo2 is the king in socket 939 currently.
hope this helps.
