Apple iMac MC812LL-A Video Card
Integrated display adapters are not as good as a dedicated video card, generally speaking. There are two types of video cards, integrated and dedicated. An integrated graphic card is built-in to the main board, whilst a dedicated card is purchased and installed onto the main board. A graphics card processes graphics and renders images to the monitor where you can see the results. Dedicated video cards are pretty much required for most games you would play on a desktop computer like Mass Effect, Grand Theft Auto or Battlefield. Almost all newer desktops will have at least one spot available for a graphics card to be installed. At the moment, graphics card maker nVidia is the most popular in the dedicated card market, while AMD is in second.
Indications of a bad graphics card
- The monitor shows colors that are all wrong
- Your Apple freezes when trying to start up a graphic intensive game
- The screen does not always come on when starting up
- The driver does not seem to install all the way
