Wait, you bought a Gen I Phenom processor? Why? You do know that they had a TLB error and that the fix reduced their performance by as much as 15%, right?

Any motherboard with an AM2 or AM2+ socket will support that processor, though. Should be easy enough to find, it isn't as ancient as Socket 939. As for that ASRock board, I can't fault it. I have an ASRock, and it's been nothing but awesome so far.
