I've upgraded the GPU in the gaming PC to a ATI 480 8GB. Playing back a HEVC.x265 on this PC is fine, although it is a quad core computer.

On the desktop it's a dual core, but the GPU is a few years old, a ATI 5450 or something like that (£30 or so) with the same file HEVC.x265 is a bit juddery at times. Is H265 more demaning on hardware? H264 played fine even upto 1080p I think.

Do the new GPUs support H265? Also if I upgrade to a freesync monitor I'd like both to output at the supported 144hz or higher than 60hz for windows desktop. What budget ATI card has freesync, passive and H265 hardware decoding?
 
4k tv?

hevc is decoded by the cpu if gpu has no hw decoding, though kabylake, 1q 2017 should handle it all, thats why your old dual core has juddery playback , though it may depend upon which playback software you are using.
 
yeah most likely ati 5450 has no hw decoding for that new video formats, ati 480 probably has as CPU usage is virtually nil - obviously quad core but even so very low, compared to 95-100% CPU on the dual. Bit like last time, H263 720p was ok on integrated GPU but 1080p was not, getting dedicated ati 5450 reduced that to 25%.
