In case anyone else is struggling with getting 4k @60hz over DisplayPort, there's an important step that's often not clearly spelt out:
Make sure your SCREEN is set to DisplayPort 1.2 <- this is in the physical screen's configuration, not anywhere in OSX.
I wish someone had told me this before I wasted half a day on it.
(FWIW I have a GTX660 and an Asus PB287Q on DisplayPort, and an older Asus monitor on DVI. 10.9.3, have yet to try 10.9.5)
