Lenovo ThinkCentre 9645 Video Card
There are really only two kinds of graphic cards, integrated and dedicated. An integrated graphic card is built-in to the main board, while a dedicated graphics card is an individual piece of hardware that is bought and installed separately. Integrated, or onboard, graphics are almost never as good as dedicated graphic cards, generally speaking. Currently, nVidia rules the dedicated card market, while AMD is in second. Dedicated video cards are pretty much required for most games you would play on a desktop computer like Battlefield, Fortnite or Far Cry. Both an integrated and dedicated video card processes the input and sends the rendered images to a monitor where you can see the results. Most new desktops should have at least one PCI Express slot available for a graphics card to be installed.
