If your video card/graphics adapter is different.

If you do not have an AGP video card, your card will be a PCI version. This means it will simply be installed in one of your open PCI slots.

If you are installing a separate 3D Accelerator card.
Some people decide not to buy "combo" cards that handle both 2D & 3D graphics. If you are installing a separate 3D Accelerator card, simply install it as you would a video card in a spare PCI slot. Consult the manual that comes with your 3D card for making final connections using the supplied cable.

The procedure is identical to installing the network card. See our parts list for recommendations regarding modems.
