Turned out the gtx 660 handled 4k pretty well, the problem was the video player. I had to try quite a few before I found one that worked. Maybe on a newer, more powerful system it wouldn't be such a big deal, but on this minimal aging one it seemed crucial that the video player efficiently decode and use hardware support. Even with proper configurations many of them are less efficient than others. VLC performed terribly! mplay/smplayer almost. KODI works
