I can already run guild wars on my computer with ndivia mx420 64mb video card(I know...its seriously outdated)but could I also run it on intel accelerated graphics with 128mb video card, or does it have to be ndivia/ati brand?
Personaly I would upgrade your video card to the best that you can afford. Manufacturer doesn't realy matter because all of them are almost equal now. Just make sure it will go into the computer that you have (must get an AGP card if that is the slot you have, PCI-Express card for that type.)
