How to change vidoe BUS

[RAT-9]

hey guys,
my friend has a problem with his video card. its a appollo 6800 AGP. 128 mb. the info on his card saidit was PCI bus. BF2 runs horribly on his PC and i have a 6600 gt which is much much better. any ideas ?
thanks

its probably a driver issue. download the latest nVIDIA forceware and install it
