A graphics card is primarily designed to remove the graphical processing tasks from the processor or RAM. It includes a dedicated graphical processing unit (GPU) and a dedicated RAM that help it to process graphical data quickly. Like most processors, a graphics card also has a dedicated heat sink to keep the heat out of the GPU. A graphics card enables the display of 3-D images, image rasterization, higher pixel ration, a broader range of colors and more. Moreover, a graphics card includes various expansion ports such as AGP, HDMI, TV and multiple monitor connectivity. A graphics card can be integrated within the motherboard or be added on as an extension card.
