Lenovo ThinkCentre Edge 91Z Video Card
A dedicated graphics card is necessary for any high-end games you play on a desktop like Mass Effect, Grand Theft Auto or Battlefield. Most newer computers should have at least one PCI Express slot available for a video card to be installed on the motherboard. There are really only two kinds of graphic cards, integrated and dedicated. Integrated is built into the motherboard, while dedicated is a separarate piece of hardware that gets installed. A video card processes the input and sends the resulting images to an external monitor where it is displayed for you. Integrated video cards are not as good as a dedicated video card, generally speaking. At the moment, graphics card maker nVidia is the most popular in the dedicated video card market, while AMD is in second.
Some warnings of a defective video card
- The monitor produces stretched or elongated pictures
- The computer reboots when starting a game
- The display does not come on when starting up
- A driver for the video card cannot install correctly
