    I have the first generation of aluminum iMacs, a 20" Intel Core 2 Duo (August 2007) with the baseline graphics card (128MB ATI Radeon HD 2400).

    Would my performance suffer if I attached an external display (probably another 20" display)? Does my graphics card have the extra power to run the display? Thanks.

    It would slow down the performance but it will work fine.
