A top end CPU and vid card... to play World of Warcrack? WoW will play on integrated graphics, so there really is no need to go all-out on a WoW build.
The 9600 is a good bang for the buck card, so I would keep it. A low-to-mid range C2D would be plenty enough to handle the game. The mobo does not have to be bleeding edge or thee digits to do good service.
WoW is an older game, and the expansions are not much more intensive than the original game. We don't have to recommend over-the-top builds every time... let the build suit the purpose.
