TIf you're interested in CPU Software Decoding, I can vouch that an i5 4590 can do all my 24hz UHD remixes around 80-95% without dropping frames.  I have a 4.4ghz overclocked i7 3770K that does it much better too.  That said once you get into 30hz and high bitrates like 120mbps or higher, with the Jellyfish examples, it starts to go to hell.  However I've been yet to find a UHD Remux that I could not playback.

Thanks, so far I am looking for something cheaper. But I will have it in mind.

This will do 10bit 4k. But everything else you run will be slow.
