Lenovo ThinkStation 6449 Video Card
A graphics card computes and sends the rendered images to a monitor where it is displayed for you. Dedicated video cards are pretty much required for any high-end games you play on a desktop like Battlefield, Fortnite or Far Cry. Integrated display adapters will never be better than a dedicated video card, in general. At the moment, nVidia rules the dedicated video card market, while AMD is sitting in second place. Most new desktops will have at least one spot available for a graphics card to be added to the system. There are really only two kinds of graphic 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.
Major indications your desktop graphics card will eventually need to be replaced
- The monitor shows vertical or striped lines
- The Lenovo ThinkStation 6449 restarts when starting a game
- The screen does not always show up when starting the computer
- The driver cannot install like it should
