Graphics Cards : Why they're Important

Graphics cards (video cards) are expansion cards in a computer that generate and send an image to the display. These cards serve a larger purpose than just improving video game graphics. These cards are important to graphic designers who create ads, logos, 3-D images, and animated movies.

Computers at Pixar use high-end graphics to create their wonderful movies. At home, these cards are often very basic, fore web surfing requires little amount of graphics. Video hardware can be integrated on the motherboard, as it often happened with early computers; in this configuration it was sometimes referred to as a video controller or graphics controller. Today, basic computers still come with integrated graphics and the serve their purpose.

            Any person that plays video games knows that it’s all about the graphics. The purpose of better graphics in games is to make the games run better, faster, and look more realistic. A basic graphics card might only able to make a circle by the use of an octagon, while a better one would be able to make the circle look practically circular. The cards have RAM memory to allow quick access and help the game run smoothly.

            Operating systems like Windows and Mac OSX need different amounts of graphics ability in order to operate. Windows XP can be run with very basic settings, while Vista is much more graphics demanding. This may sound daunting, but computer technology is expanding at such a rate that current basic graphics cards would have cost a fortune in the early years of computing. Vista looks nice, but that requires a large amount of graphics.
