    After doing some research it appears the 2014 - 750m has a slight problem with throttling. But the M370X in the 2015 will throttle more than 50%. I'm not sure how accurate this is...

    Does this issue occur in OSX with professional apps and/or occasional steam games, or is this just windows/boot camp specific? Has this issue been fixed?

    Thanks

    Nvidia has a better track to not overheat and throttling
    i dont know about M370X but the M295X from the imac it is throttling in heavy tasks

    It's horrible compared to what's out there. Even AMD latest drivers don't address the M370X. Shows how confident AMD is with the graphics cards in Apple laptops. I would honestly buy the 750M option instead and wait till a newer NVIDIA GPU is released for the rMBPs.

    Even a "budget" 960M from NVIDIA would be a ton better than Apple's choice of AMD GPU. Don't say stuff about thermal constraint when there are Windows laptops with as slim a profile as the 15" rMBP with the 960M and even a 970M.

    Why would Apple release an nvidia GPU in future MBPs? It looks like they've moved all of their product lines towards AMD.

    Apple chose AMD cards due to the way OS X adresses the videocards and relies on OPenCL instead of CUDA cores from nVidia... If Apple could reduce the size of the logicboard and increase the heatsinks by a bit (including fans) they could do that I guess, we've all seen what they can do with the 12" rMB.

    Apple is always bouncing between Nvidia and AMD, no need to worry.
    Also are the MacBooks without an dedicated GPU limited by Apples bad cooling options in the MacBook. Adding another "heat source" will result in hardware throttling because the cooling can't handle that much heat at full blast.
    It helps a bit to disable the turbo of the CPU (Windows Intel XTU or in OSX with Turbo Boost Switcher) and give the cooling more "room" for cooling the GPU.

    The cooling capacity in other similar sized notebooks is often much larger than the rMBP. If you open it and look, the heatsinks are tiny.
    Other manufacturers will sacrifice some battery space to fit slightly larger heatsinks in, for example.

    I just sent mine off because the heavy use it saw fried the graphics card, or at least that's what the kernel panics keep suggesting
