The graphics card is a nvidia 9800, pretty beefy card. I don't know if I need to upgrade everything in my tower. I wish I knew what kind of mother bored and processer I had, but I do know my processer is dual core. IDK if my mobo can handle the I7 quad or not. And yes I can build a PC, however I did not build this one and therefore have a problem figureing out all what is in it. the power supply is 1000 watts so I think I should be ok there. I have 6gig DDR2, and the only thing Ill be useing the PC for is multy-boxing wow. I mean brousing web pages and email and such, but nothing major. And I want a ballance, as I don't know exactly what I can afford, Lets say I want to be able to not loose my toons on epic flyers, but I don't mind a little lag in dal.
