When I was shopping for a new video card for my home desktop (i5-4590 CPU @ 3.3GHz 8GB Ram, 64bit win 10)
, this web site helped me decide:
Its.. well.. for a few dollars more I can get this one, then for a few more I can get this, and it goes on and on.
I ended up with the RTX-2070, not super expensive, but not cheap either. (Now they have the RTX-2070S Sheez)
This card runs the free DJI simulator mind boggling great. One can see the prop wash blow individual grass blades when hovering near the ground.
Anyway, it plays back 4K videos with most viewers without problems. A few players have issues. Never see any issues in 1080
YouTube 4K playback works really, really well.
When I run 4K raw (DNG) videos though different editors, it processes anywhere from 1x to 2x quicker than the time recorded.
When I use my Laptop: Windows 10/ Intel Core i7-2620M CPU @ 2.70GHz, 12GB Ram, 64-bit Operating System I7 4 core, a 10 minute 4K video can take 90 minutes to process.
I needed to tweek VLC's Input and Codec settings to play back without jerky-ness, see:
My Platform: Windows 10/ Intel Core i7-2620M CPU @ 2.70GHz, 12GB Ram, 64-bit Operating System VLC Media Player 3.0.8 Vetinari Press Ctrl-P, Select Input/Codecs, Change Skip H.264 in-loop deblocking filter from None to All.

Usually a "slow" machine will process video just fine, it will just take forever. The playback is the real issue.
