Lenovo ThinkServer 2592 Video Card

There are two types of video cards, integrated and dedicated. Integrated cards are built-in to the computer itself, while a dedicated graphics card is an individual piece of hardware that is bought and installed separately. At the moment, nVidia rules the dedicated video card market, while AMD is sitting in second place. Integrated, or onboard, graphics are almost never as good as dedicated graphic cards, in general. A video card processes graphics and sends the resulting images to an external monitor where you can see the results. Most new desktops will have at least one PCIe slot open for a dedicated video card to be installed. A dedicated graphics card is pretty much required for most games you would play on a desktop computer like Far Cry, World of Warcraft or Battlefield.
