"Hello. My name is Mark, and today I'm going to talk about the difference between a PCI and an AGP video card. Some of the obvious differences are that the PCI video card requires a white PCI slot to install on your computer and has a maximum of eight megs of memory, which is pretty slow for today's video requirements. Whereas an AGP card can go much higher. I have a 512 meg AGP card on my computer. So, a great difference from eight megs. The AGP card requires an AGP or an accelerated graphics port in your computer, which is usually the brown slot, in order to be installed. AGP cards plug into a slot of 2X, 4X, 8X, I think even up to 16X. But the main difference between the PCI and the AGP video card are the capabilities and the speed. And that's basically the difference between AGP and PCI."
