Can future retina iMac contain two GPUs?

[Sedak]

Hi,

I'm looking for retina iMac impatiently. I wish it would have size between 23" to 25" (with no or very minimal sides frame to save space) for plain 4k. I know single modern GPU can hadle 4k well, games would most likely need to run in 1080p. Does it make any sens for Apple to put two GPUs inside? I know some professional software can benefit from that, it is already in Mac Pro (alright, there are Pro cards). But can other Apps, games and future Aperture (hope there is one) benefit from that with little customization, or is such support usually pain in the ass?

Thanks,
Sedak

There are a few laptops that already have the dual nvidia GTX 880M setup.

The 880m doesn't get very hot so putting two in a imac would be possible.

Yet i think its very unlikely that apple would go for such a costly solution.
