    Does the standard 680 GTX Mac Edition support 4k 30 Hz? I have read that the 680 GTX from Macvidcards support 4k 30 Hz, but is this a modification from Macvidcards or normal for this card?

    Thx for infos

    The GTX 680, as well as many other modern GTX cards, support 4K resolutions, though OS X is a limiting factor. The GTX 680 will output 4K resolutions through Displayport, and at this time OS X supports up to a 30 Hz refresh rate, with 60 Hz support coming in 10.9.3.

    Does that mean in Windows the 680 can do 4K at 60Hz now?

    I believe that the latest NVIDIA drivers will do 4K over Displayport 1.2 in Windows on the GTX 680.

    Interesting. My GTX 660 comes with DisplayPort 1.2, you could probably manage dual HDMI 4K via the HDMI port and a DisplayPort to HDMI adapter. Pretty crazy they would dumb down the card for the Mac version.

    EDIT: All the more reason to buy a PC card and flash it yourself. ;)

    I wondered about this, too. My guess is that the specs where written according to the possible capabilities of the Mac OS available at the time of the release of the EVGA 680GTX Mac. E.g. it still lists OpenGL 3.2 and OpenCL without any version.
    But since OS X 10.9 the card supports OpenGL 4.1 and OpenCL 1.2. The official specs have never been updated by EVGA. I hope the same is true for the display port. The hardware should be able to meet the DP 1.2 specifications. Perhaps somebody will give it a try once 10.9.3 is released and we will know for sure.

    Has anyone a 680 Mac Edition and a 4K display to test it? :D
