Hardware acceleration of the decoding is useful, but only with edge cases (you're not re-encoding 50 years of ABC TV are you?), certainly more memory is useful (but can your OS use the extra RAM), faster IO is always better, but for a home user, you'll get by.
As you pointed out VLC does a good job with both; I would stick with it as the preferred playback tool.
For what it's worth, reading the user manual for the K-1, page 119, the movie recording format is MPEG-4 AVC/H.264 (MOV).
Of course, on the flip side, Apple is End Of Life QuickTime on
Windows PCs.
I am pretty sure you are mixing up H.265 (HEVC) and H.264.
"Almost" everything today is encoded in H.264 (also 4k material like youtube), because there is wide support for hardware encoding / decoding.
This is not the case for H.265, I believe the Skylake CPUs were the first to fully support hardware encoding + decoding and it is implemented therefore into typical encoder's like ffmpeg atm, if not even already done (not up to date here).
Otherwise you might need a dedicated graphics card which has the hardware decoding support.
H.265 content is still slowly showing up, in 4k BRs for example (which is why you need a new BR-player for your TV which can hardware decode that stuff).
The advantage of H.265 is smaller file with same quality encoding, but this costs hardware ressources for encoding and decoding. Thats why we need the special CPU instructions to speed this up. Do not even mention H.265 10bit encoding (usually we use 8bit atm), this is even worse.
If you want to test your PC, play the 4k "sintel" file in 4k and watch your CPU usage

BTW: Anybody remembers trying to play DVDs on PC without hardware-acceleration in the early days
