Voodoo 2 cards are 3d only cards. You leave your agp card in and put the voodoo 2 in a pci slot. The pass through cable runs from the video output on your agp card to the video input on the voodoo 2 and then your monitor connects to the video out on the voodoo 2. All of windows is run with your primary video card. When you go to play games, you can select which card you want to use to play games. For example, If I have a tnt 2 card in my agp slot, and a voodoo 2 in my system also, when I go into unreal torunament and detect my video hardware it would come up with 3dfx glide and direct 3d as rendering options. If you choose the glide api then UT will use the voodoo 2 to run. If you choose the direct 3d option, UT would use the Tnt2 card.
BTW. Your primary video card does not have to be AGP. It was just an example.
