By the way a friend of mine has an Athlon 64 +3200 with a Radeon 4350 and he plays alot of MMOs like Guild Wars and stuff so it seems fine for that. It was a huge upgrade from is 2.7GHz celeron
. He likes to play alot of those free MMOs and it seems fine for that so if that's what your brother is gonna do you should be good. You may wanna add another stick of RAM there.
