The GTX 960 is a very popular card right now in the video editing community because of it's built-in accelerated H265 encoder/decoder. H265 (HEVC) is notoriously very computationally intensive (due to it's high compression). My laptop can playback H265 video in 720p and 1080p resolutions with no problems, but it chokes and stutters badly with 4K video. On the other hand... my laptop has no problems playing back 4K video encoded in H264.
The integrated GPU of the new 6th generation Intel Skylake CPUs also have H265 encoder/decoder acceleration built-in.... although the Intel speeds up the rendering of H265 by a factor of about 2.4 times...Vs.... 3.3 times faster for the Nvidia GTX 960 over non-GPU (CPU-only) encoding alone.
A couple reasons the new H265 codec will eventually overtake H264 in use is it's roughly 2:1 compression ratio advantage (roughly half the file size with no loss in image quality) and also it can be at a lower bitrate (great for streaming over the internet) while maintaining that image quality.
The disadvantages of H265 is higher hardware spec requirements for smooth playback and much longer render encoding times (that's where the GTX 960's H265 encoder drastically shortens rendering times). Another disadvantage is that most video streaming sites including YouTube don't currently accept videos uploaded with H265 encoding. So you must convert the video to another codec like H264 (and thus increasing it's file size and upload time) for those sites to accept it.
The Samsung NX1 is one of the only cameras to record video in H265 right now and many video editors don't fully support the codec yet. My Sony Vegas doesn't yet support it officially... although there is a rigged-job German 3rd party freeware plug-in out there that at least lets you load, playback and convert the video to other formats... but does not encode in it.
My PowerDirector 14 editor on the other hand officially supports loads, edits and renders in the format with no problems.
