I have a 17" Macbook Pro that has 8 gigs ram (it's the last 17" MBP Apple made) that is struggling when it's connected to my 27" Apple Cinema Display. I'm using Ableton Live 9 (Digital Audio Workstation that is similar to Logic) and the fan will get loud and the computer will stutter and have lots of latency when trying to keep up with playback in the program. I also experience this when watching youtube videos that are high-resolution. Now, if I unhook the Apple Cinema Display, the Macbook Pro will actually run fairly well on all the above mentioned programs. Has anyone else experienced something like this? It's gotten to the point where I'm considering getting a Mac Mini because I really like the screen real estate and I don't really take my Macbook Pro places anymore.
