I can't be positive because I don't know what different video cards are made that run on Nvidia drivers..(PCI vs AGP).
To determine if you have a PCI or AGP video card, open the case and look at the card the monitor is connected to. Look at the slot or socket the card plugs into on the motherboard. Is the slot / socket white?..if it is, it is probably PCI. If the slot / socket is brown, and set further back on the motherboard than the rest of the slots about 1 inch...it is probably AGP.
On every MOBO i've seen with an AGP slot it's on the top so when you look at the back of the box you should be able to tell if it's PCI or AGP, assuming you know you have an AGP MOBO.
ok never mind its not that big of a deal sorry to stir up a wirl wind Im happy with the video card I have. have a great day I dont know to much about computers so I will take it to a shop and if i need a new one they will do it the card i have is not very old maybe 6 months or a little bit older it plays rtcw ok so i will stick to it .. thanks val
