Does nMP utilize both GPUs for running the displays?

    In the performance sense I mean, I feel like it may not. For example games seemingly run off just 1 GPU so I'm not sure if Apple did the work for OS X itself to take advantage of offloading the work of displaying content powered by both GPUs simultaneously.

    Thoughts? Am I crazy? etc.

    Yeah seems like small bummer.

    I plan to run 3 30" (2560x1600) monitors and I worry a little about that many pixels being powered by 1 d700. Ya ya I know this thing can power 3 4k monitors however if the nMP (at least this 1st gen) is anything like the way the 2012 rMBP performs (i.e. that 1st gen as well, barely being able to power the screen without noticeable lag) then I may see some issues...

    the rMBP drives it's display just fine if you're not using the intel integrated GPU. just turn off the integrated GPU in sysprefs->energy saver.
    I really doubt a dedicated d700 gpu will have any problems driving a 4k display if a nvidia 650GT can drive a 15" retina display.
