AGP (Accelerated Graphics Port) Slot
The AGP slot allows you to insert the AGP graphics card. AGP is an
interface specification designed for the throughput demands of 3D graphics.
It introduces a 66MHz, 32-bit channel for the graphics controller to directly
access main memory and provides three levels of throughputs: 1x (266Mbps),
2x (533Mbps) and 4x (1.07Gbps).

Five PCI slots allow you to insert the expansion cards to meet your
needs. When adding or removing expansion cards, make sure that you unplug
the power supply first. Meanwhile, read the documentation for the expansion
card to make any necessary hardware or software settings for the expansion
card, such as jumpers, switches or BIOS configuration.
