Just have to get this gripe out...
I love Asus. As far as I'm concerned, they make great stuff at good prices. Of all my system builds, the mainboard has always been an Asus. One time I got two faulty motherboards in a row but Asus replaced both for free, no questions asked, so I'm happy overall.
My current system uses an M3A78 mainboard. Socket AM2+, 140W CPU support, AMD 770 chipset, and pretty sturdy. Right now I have a Phenom X4 9950 plugged in and I wanted to upgrade to a nice, power-efficient Athlon II X2 255.
I'm sitting here with that very processor in an unopened box for the past month, and the last BIOS update which included new CPU support for this motherboard was 14 months ago, and there appears to be no sign that Asus will release further BIOS updates to support the slew of new processors AMD has released since then. Infact the last BIOS update for my motherboard was released before the new year, a beta version addressing a completely obscure Windows 7 WHQL bug.
Meanwhile, all the numerous derivatives of this model of motherboard - M3A78-VM, M3A78-Pro, etc. - can handle all the latest Athlon II and Phenom II processors released so far. They see regular BIOS updates every few months, it would seem. Sometimes every few weeks.
I must say that I'm very disappointed in Asus for the first time. And the first time always hurts the most... (cue "Love Hurts" by Nazareth)
C'mon Asus! Update this BIOS already. Shouldn't be too hard a task; it seemed pretty easy for every other M3A* motherboard you own!
