Dell OptiPlex 755 Video Card
Integrated display adapters are almost never as good as a separate video card, generally speaking. There are two types of graphic cards, integrated and dedicated. An integrated graphic card is built-in to the main board, while dedicated is a separarate piece of hardware that gets installed. A graphics card processes the input and renders images to the monitor where it is displayed for you. Today, graphics card maker nVidia is the most popular in the dedicated video card market, while AMD is in second. Most newer computers should have at least one PCI Express slot available for a video card to be installed on the motherboard. A dedicated graphics card is usually necessary for high-end games on the desktop like Overwatch, Battlefield or Far Cry.
