Well i'm not going to upgrade it...there is no point all i want to play is guild wars...and the other reason that it's no reason for me to get a gammers computer is that i have dial-up and i'm very limited to games that i get..so now all that i want to get is a graphics card but i need to know whats up with like the Memory Interface: 64 bit.......what does that mean does that mean u have to have a PCI card with a 64 bit because i think mines only 32. Also i looked on HP's website and it says that my graphics card is AGP Interface, what does that mean does it mean i need a AGP graphics card instead of PCI?
