Review at Anandtech (http://www.anandtech.com/show/8526/nvidia-geforce-gtx-980-review)

Full HEVC encode/decode support as well! Sweetness!

Finally! I've ordered the 980.

It also supports eDP 1.4, which has a spec for Adaptive Vertical Sync that is not Nvidia's proprietary G-SYNC technology.

There is indeed a HEVC encode/decode and it claims to also encode H.264 4K at 60p from gameplay.
