yes i have an emachines intel celeron 1.8GHz PC with 2 sticks of 128MB PC2100 133MHz RAM. Running on XP PRO. Is this enough to play games such as Battlefield 2, World of Warcraft, City of Heroes. also what kind of graphic card can i get away with using. Im not trying to spend alot of money. I was thinking about using an XFX GeForce FX 5500 (256MB)(AGP) also what is the difference between using an AGP card and a PCI card I dont quite understand. and what is the difference between a PCI video card and a PCI Express video card.
