I'm only running one 4K monitor which is the Samsung U28D590D but it runs fairly well on OS X 10.9.2 at 3840x2160 and 60Hz (Single Stream). This is on an nVidia GTX670 video card via its only DisplayPort. This is also flanked by two 27" Asus 1920x1080 monitors via HDMI and DVI respectively. I was also able to connect a fourth 27" 1920x1080 monitor via the second DVI port.
I had to update to OS X 10.9.2 from 10.9 in order to get the Samsung U28D590D to function at 60Hz though and my video card would only be able to support 3840x2160 at 60Hz on its single DisplayPort.
So I think its possible to run two or possibly more 4K monitors on one system but achieving best performance 60Hz wouldn't likely be possible from one video card. I Admit though that 30Hz on the Samsung U28D590D looked really good and was very responsive.
OS X 10.9.3 should have better 4K support though so you should be good to go if you have the budget for the hardware.

Hey Octavean,
I just got the same Samsung 4k monitor but I'm having trouble with mine via display port. Works fine via hdmi but if I try to boot with display port I get a message saying memory allocation error. Did you experience this?
If I plug it in after booting it works fine and Windows 8.1 recognises the 3840 resolution automatically but OS X only shows 1080.
Thanks

No I didn't experance that problem or anything like it.
My guess is that you are using a different video card then I am using. If your system specs are correctly listed here then it looks like you are using Intel integrated iGPU. I'm no expert on any of this but my guess is it might have something to do with the allocated memory to the Intel iGPU but I could be way off.
My system is based on an Intel Core i7 3930K / ASUS P9X79 Deluxe with GTX670 video card. I have no experance with Intel integrated graphics.
