Depends. Some of the Kepler-based GTX 900 series (really just rebranded
GTX 800-series cards) max at 2560x1440 or 3072x1536.

Radeon R9 series cards can do UHD; the R7 and R5 cards max at at
2560x1440 and 1920x1200 respectively.

nb. I lost interest in following the industry over the summer so my
information may be a little dated.

If the display is physically large enough to make use of that
resolution. UHD at less than about 35" at 16:9 and everything will be
too small to comfortably see without magnifying to compensate. At which
point the UHD screen is a waste of money.

nb. UHD and 4K are not synonymous. UHD is a set of specs for video
displays operating at 3840x2160. 4K is a set of digital camera and
editing specs for video recorded at 4096x2160. UHD content is, by
definition, not 4K. It must be scaled or cropped to fit. Chances are,
any display labeled either "4K" or "4K UHD" is actually UHD. An actual
4K display would be extremely wide relative to the vertical size (1.9:1
aspect ratio).
