too many vendors boycott the upgradebility they just dont want to release a simple bios update because they want to force costumers to buy a new motherboard. it would anger me i would have bought a am2 motherboard and the vendor was such a bastard to boycott the upgrade.today those bios updates are rare too find. so far i have only few vendors who upgrade there bios. apperently ASUS support it the best so that is why i will choose ASUS above all those cheap bastards from now on
