and its chipset.

The amount of the Video Memory is also responsible for the color and screen
resolution. The higher the amount of the Video Memory, the higher the color
depth the video card can render. On the other hand, the type of the Video RAM
is an another factor that affects the speed of the video card.

The Video Chipset is the brain of a video card. It similar to the CPU in the
motherboard. However, unlike the CPU which can be fitted with different
motherboards, certain Video Chipsets can only be fitted with certain video cards.
The Video Chipset is responsible for processing the special video data received
