I am upgrading my two boys' computers for WOW they are have similiar specs to the one listed here. I too am looking for a graphics card. Everyone is recomending the GTX 460 as the best one without having to upgrade their power supplies. They have 3.2 GH proccessors and 4 GIG of RAM. They have PCIE slots, but they only have a standard power supply. I was tols you could get this card for around $100.00.
