Intel UMA (Unified Memory Architecture)

UMA (Unified Memory Architecture) just means the graphics adapter uses system RAM as video memory. It's ok for everyday use like surfing the web, watching movies etc but it's not good for gaming.

For gaming you'll want a graphics card made by Nvidia or ATI/AMD, not Intel's graphics.
