The graphics chip must be powerful enough to display and redraw the user interface quickly as you work. If your intended notebook usage includes high-quality image processing, Computer Aided Design, multimedia or games, you will need to look for ahigh-performance graphics chip. However, normal office applications and modest presentations, can be handled very well by a standard chip. What is important is the amount of video RAM (4 MB is normally standard, with 6-8 MB required for true colour at higher resolutions), since it has a key impact on the maximum number of colours that can be displayed.
