I have an old & slow pentium II 400mgz 256mb ram onboard matrox g200 8mb onboard graphics PCI slots,can this be upgraded?will a ATI Radeon 7000 64mb DDR PCI VGA card work??
Not all boards with on board graphics will have an AGP port for graphics cards. I think you'll be able to use a PCI card though.
Just make sure to disable the onboard graphics chip otherwise you probably won't notice any impovement.
