The Peripheral Component Interconnect or more commonly known as PCI is a standard for connecting a lot of devices inside your computer to extend its capabilities. Devices like sound cards, modems, NIC, TV Tuners, and some video cards have at some point or another have used the PCI port. The latest version of PCI known as PCI express is a much improved version in terms of speed. PCIe uses a serial interface instead of the old parallel interface used by PCI. It also utilizes individual buses for each of the devices connected to it instead of a shared one like what PCI uses.
2) AGP also is in a similar position as PCI now, and chipset manufacturers are killing AGP motherboard support in favor of the much faster PCI Express interface. This means you are looking at a forced transition in the graphic sector, thus you really don't have a lot of choice in the coming years.
