In computing, a video card, graphics card or graphics accelerator is a special circuit board that controls what is shown on a computer monitor and calculates 3D images and graphics.
A video card can be used to display a two-dimensional (2D) image like a desktop, or a three-dimensional (3D) image like a computer game. Computer-Aided Design (CAD) programs are often used by architects, engineers and designers to create 3D models on their computers. If a computer has a very fast video card, the user can create very detailed 3D models.
