Yet if you bought a Nvidia 960 about 1.5 years ago when I did (because it supported HEVC, and I upgraded my 10 year old plasma to a 4k TV), it can do it for you. My HTPC can happily play back high bitrate 4k HEVC content without as much as breaking into a sweat.

Sadly Netflix doesn't see it that way and demands that I update my perfectly functional i7-2500 system to a newer one to play back their 4k content.

(Sorry, slightly OT rant).
