    Bootcamp - 3840x2160 via display port think it can run at 30hz via hdmi also I think.

    OSX is another question, not quite yet I think according to MacVidCards 4k thread a while back..

    There's also running vs will it run what you want it to... It's a 2gb card if I remember correctly, and these seem to struggle with games in 4k.

    The chosen resolution of a Youtube video, and whether it can be played, has nothing to do with whether the GPU will drive a 4K/UHD monitor. The 680 Mac Edition is a horrible investment at between 500 and 600 USD when you can buy a far more capable card for half the price. If you absolutely need a boot screen, MacVidCards can fix you up with an assortment of flashed/modded cards. Originally the Mac edition was not listed as supporting 4K, only 2560x1440 or so. Regardless, even if a driver update enabled it, the Mac version is still a huge waste of money. Most of the PC versions of the GTX 6XX and higher now support 4K. Specs are on the Nvidia website. My 670 drives a UHD (a/k/a 4K, unfortunately) with no problems at all using the latest drivers.

    Yes, both the HDMI and Display-port support 4K.

    1x HDMI: up to 4K HD, 4K 16:9, and 5K @ 60Hz
    1x DisplayPort: up to 4K HD, 4K 16:9, and 5K @ 60Hz

    HDMI on the GTX 680 will NOT do 4K@60Hz. It is limited to 30Hz.

    Display Port will do 4K@60Hz.

    I also do not know if the GTX 680 is capable of driving a 5K monitor.

    gtx680 can't drive 5k monitor because it has only one DP output port

    gtx680 will run just fine 4k display at 60hz, but will not show bootscreen on it, you will get output only once osx is booted.

    pastychef: nice necro.

    I have a 2GB NVIDIA GeForce GTX 750 Ti running a 4K monitor using DisplayPort on my Linux box. It has no problems running games at 4K resolution at 60 FPS -- even with 2X FSAA.

    I am running the GTX 680 on a Mac Pro 5,1 with Yosemite and can't get any higher res than 3200 x 1800 using ANY of the cables at ANY res. Any ideas?

    When you are in the Display system preference, hold the Option key and click the Scaled button to access all the resolutions.

    DIsplayport is only one to use. And SST 4K is much easier to deal with.

    Depends on the game. But yes, newer games e.g. GTA V with maxed details uses already 3.2 GByte V-RAM @ 1440p.

    Therefore I would choose GTX 770 4 GB if a Kepler card is needed, not a GTX 680 2 GB or a GTX 680 4 GB.

    I heard for 4K/5K gaming 6 GB V-RAM is recommended for actual games.

    There are 4GB versions of the GTX 680. The advantage of a GTX 680 over other Kepler cards is that they can be easily flashed for EFI boot screens.

    Yes, I agree. And actually there is only a minor performance difference between GTX 680 4 GB and GTX 770 4 GB.

    Important is to have 4 GB V-RAM when running recent games. 2 GB are outdated.

    And maybe 6 GB for 4K.

    THANK YOU!! THANK YOU!! THANK YOU!! THANK YOU!!
    I could not figure out why the max resolution for my Samsung U28E590 was stuck at 3200x1800. I knew the NVIDIA GeForce GTX 750 Ti GPU would drive full 4k over Displayport. Why in the hell does Apple conceal these higher resolutions by default? I'm running El Captain 10.11.6 on a Mac Pro 3,1. I wonder if they mask these resolutions based on the age of my machine?
