Types of Video Card

There are three main types of video card commonly in use.

• PCI Express
• AGP
• PCI

PCI Express is the most current, and fastest, of the video cards. If possible, you will likely want to install a PCI express video card. Figure 5.1 shows a PCI Express video card.

Before PCI express the most common type of video card was the AGP card. AGP cards still give great performance. If you have only one video card in your system you will want to make sure it is either AGP or PCI Express. Figure 5.2 shows an AGP video card.

The oldest style for video cards that I will discuss is PCI. You can see a PCI video card in Figure 5.3.

You should not use a PCI card as your primary video display card. PCI cards are to slow to play any of the more advanced video games, or to show video. Besides, the price difference between PCI and AGI/PCI-Express is minimal.
