I recently was given a Dell Dimension 4400 with P4. I decided to make it for playing WoW. I already upgraded to a gig of ram and put a new HD in it and now i need a cheap graphics card cause i spent all my money.What can i buy that can get the job done, cause the one that is in this thing now is some crappy 64mb card that is just god awful and is all glitchy with the artifacts playing WoW. some ssuggestions pls. Thankyou in advance.
