Probably not really specific to Kaby Lake, but what are the differences between Windows and Linux as OS?

Am looking for a device that can play 4k@60 4:4:4, HDR and HD audio (bitstreamed) ... 3D is a plus, but I could use my RPi2 for that

Thanks in advance!

If you want an OS which can play 4K content and 3D MVC, then Windows 10 should be your first choice. If you don't care about 3D then is LibreELEC also a good one. There is no support for HDR content yet on both platforms.

The main downside is that there's hardly any 4K content available to playback it with Kodi. I would wait until more content is available or the possibility comes to rip your own UHD-Blurays. Right now this isn't possible yet.

Thanks, so Windows is only needed for 3D ... that makes it clear

I know there is little to no content yet for 4K / HDR ... but going for a new device, you want it a little future proof.
The only content I got now is 1080p and some with HD audio, but since I got the rest of the equipment, would love to get more out of it
