Lenovo ThinkCentre 2121 Video Card
There are really only two kinds 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. Almost all newer desktops will have at least one PCIe slot open for a video card to be added to the system. A dedicated graphics card is necessary for any high-end games you play on a desktop like Overwatch, Battlefield or Far Cry. Integrated video cards are not as good as a separate video card, in general. A graphics card computes and sends the rendered images to a monitor where you can see the results. Today, graphics card maker nVidia is the most popular in the dedicated video card market, while AMD is in second.
