Like the title says, I was wondering if the display port(s) are still tied to the dedicated GPU. I have an Early 2011 15 MBP and the dedicated GPU is tied directly to the external display port (in my case the MDP/ Thunderbolt port). When I want to run an external monitor, I am forced to use the dedicated GPU as that is the only thing wired to the external display port (I know it made no sense that the internal GPU was fine on the models without the dedicated GPU to drive an external and the internal at the same time, so why apple chose it this way makes no sense to lots of owners). I am contemplating my next upgrade and was wondering if this still was the case. I like the dedicated GPU for when needed, but misty of the time is not needed for my day to day activities and would like to be able to use an external monitor without having to have the dedicated GPU running to save battery life and have things run a little cooler without the dedicate GPU kicking in. Are the new models also still configured this way, or is it now possible to drive an external monitor and have only the internal GPU running and not the dedicated (if it exists within the system)?
