A video card provides signals that operate the computer monitor. A computer will have either an AGP graphics or PCI Express (PCIe) graphics. With the arrival of graphic intensive games, the video card manufacturers have integrated a processor and memory on the video card. The greater the memory, the faster the processor, the higher the quality of the game produced by the monitor.
Most mid-range and faster graphics chipsets no longer support the PCI slot. Besides faster throughput, AGP has two other big advantages over PCI for video:
AGP has a dedicated direct connection to the processor instead of sharing bandwidth with other PCI slot and motherboard devices.
AGP can use onboard or motherboard RAM for handling 3D textures.
Some of the latest video cards in the market are AGP PCIe, Radeon 9600 XT, GeForce 6800 Ultra Radeon X800 XT, etc
