Hi, i have a 4th gen p4 in a computer that pretty much has no use, I really only use it when my gf brings her friends over to play games, they are all into wow. I have 4 computers not including my own with good hardware, the slowest computer has an fx 6300 and a gtx 660. But myself and my gf take up 2 of the 5 computers, then if she brings more than one friend all of the computers get taken up. The reason i asked about the two cards is my friend owned his own shop, and he still has stuff left over. He said the 460 would be 30 new or the 470 would be $60 new. I was thinking about buying it because my friend wants to start coming over to game as well but I only have the P4 computer left, it has 8 gigs of ram also. So how would these two cards be with a p4 for wow.
