A PCI is an older slot used for graphics cards. AGP is a newer one, and there is even a newer one than that which is PC Express. Between the PCI and AGP, if you have a choice, you always want to go with AGP. AGP is a faster graphics card system and it allow the graphics card to talk to the processor at a much higher rate than the PCI graphics card could.
