I have a 2012 RMBP. Will I be able to run 4K at 60 hz or am I stuck at 30 hz? All the notes in the new update refer to 2013 models. Got me worried I may have been left out of the goodness.
TIA

Only Macs with Thunderbolt 2 can support 4K.
That may be true for Macbook, but not entirely true for desktop, my 2009 Mac Pro not even have thunderbolt 1, but can run 4k or even higher (up to 5160x2880).
And it support 4k 60Hz via the mini display port.

The problem is, the native display of the ACD is still 2560x1440. Selecting 5120x2880 will render things at a tiny size and look mushy on the ACD. So in the end, your GPU is still driving a 2560x1440 display. Unless, the GPU renders everything at 5120x2880 and then scales back down to 2560x1440, which I doubt is likely.
In fact, it is render at 5120x2880 and scale down to 2560x1440.
This is the screen capture, which is actually at 5120x1440.

And I can plug it into my 4K TV to enjoy the real 4K output. However, since I only use HDMI when connecting the TV. Therefore, I can only get 4K 30Hz. But there is no doubt that there is no absolute relationship between 4K and thunderbolt 2 in Mac.
interesting! thank you for sharing that.
No worries, sharing is caring
I have a nMP6,1 8-Core with dual 6GB FirePro cards and dual 27" Cinema Displays. Do I need 27" Thunderbolt models? You mentioned this is over Mini-DP. Why can I not get those resolutions??
Thanks!
I installed Quartz debug to play around with the 720 HiDPI, most likely that unlock all these resolution to me.

OK, Let's try another simple trick.
Hold down the "option" key, and then click "scaled".
I really have no idea why, technically the D700 is the HD7970, and able to do everything that my HD7950 can do.
I could only assume because it is an Apple native card, so Apple easily lock out those "extra options" from your card.
Anyway, I guess once you connect your new Mac Pro to a 4K display, those options may just pop up.
At least we know that 10.9.3 can do that, and your nMP is completely capable to do that as well.
The D700 is actually a W9000.
Thanks everyone for the help. Looks like I better start saving my pennies for that new RMBP! Who wants to tell my wife?

Because the 27" Cinema Display (and the 27" Thunderbolt Display) can only do a maximum of 2560x1440.
Apple currently does not sell a 4k monitor.
Of course no need to trust me. And I don't know how to give anyone a solid proof as well. All I know is how to take screen shot.
