    I game on mac and windows via bootcamp on my 15" rMBP. For some games id like to get a bigger screen such as the Apple thunderbolt display or another third party like samsung (cheaper) and hook it up to my mac.

    MY question is how much more GPU power does this draw? will i have to turn down the graphics on my games that i play with the monitor more than i would regularly need to without the monitor?

    thanks

    Only if you change resolution.

    Theres no difference between running a game on an internal monitor at 1280x800, versus an external at 1280x800.
