    # Video card in minicomputerJaap J. van Veen 2011-08-31 01:49
    I own a Shuttle XPC from 2004. It has an FN41 motherboard with an Vidia GeForce MX Integrated GPU (32MB). I had to buy a new screen which has 1920x1080 pixels. Now my internal graphics card is running short of capacity (flickering). I bought an AGP8x Videocard but the size of the computer does not allow to install the card (cooling ribs too high, MSI NX6200AX-TD512H). I have also a half PCE slot empty. The computerpower is 250Watt. Please advise for which Videocard I have to look for.
