Lenovo ThinkCentre 9640 Video Card
Dedicated video cards are usually necessary for any high-end games you play on a desktop like Far Cry, World of Warcraft or Battlefield. There are two types of graphic cards, integrated and dedicated. Integrated cards are built-in to the computer itself, whilst a dedicated card is purchased and installed onto the main board. Almost all newer desktops should have at least one PCI Express slot available for a dedicated video card to be added to the system. A graphics card computes and sends the resulting images to an external monitor where it is displayed for you. Integrated display adapters are almost never as good as a separate video card, in general. Today, graphics card maker nVidia is the most popular in the dedicated card market, while AMD is in second.
Symptoms of an ineffective graphics card
- The monitor produces weird colors or images
- The desktop freezes when beginning a game
- The screen does not always come on as you boot the PC
- The driver does not seem to install all the way
