go onto crucial.com website, do an online scan, then when its finished alot of info about your system will be on the screen, on the left somewhere it will say what type of graphics card you have
u mean PCIx and AGP, lol. go to google, type in Cpu-Z, and run it, it should tell u. if that doesnt work go get Everest Home Edition, and if u dont want that go to Start>Control Panel>System>Hardware>Device Manager>Display Adapters>pick the video card and check interface.
lol actually crucial scan worked fine for me and i got the card installed... now the game wont read my joy stick right but all other games still do any one know why?
