Video Card
Function and Importance
A video card is not needed for the computer to run. It is normally bought to increase the visual quality of 3D games such as Battlefield.
Attributes
Video cards with larger bus width and faster clock speeds are much better as the computer will process the visual data faster. A larger memory however does not make that much of a difference on the graphic card's performance.

The frequency is measured in Hertz and it tells how high or low the speaker it can play.
