The first type of video card is called the integrated video card.It comes default with the motherboard.It is installed during manufacture.It can be upgraded by installing a new video card on the computer and setting the computer to ignore the previous or default video card.The integrated video card is the least powerful.In order to play games or do rendering one needs to upgrade.
The second type of video card is called the PCI graphics card.It uses the PCI slots on your motherboard to connect to a computer. They are prevalent in old motherboards.
The third type of video card is called the AGP graphics cards.It is named for the same thing PCI cards are—the slot they connect to on a motherboard. AGP cards can have four speeds, the fastest being 8x. If a motherboard only supports a lower speed, such as 1x, 2x, or 4x, your graphics card will behave as if it is of a slower speed, rather than its real speed. AGP connections are not quite as fast as PCI-E slots due to technological limits, and as a result will not be developed to run at higher speeds. However, like PCI cards, they are more widely compatible than the most cutting-edge cards.
