Upgrading to a new PC [URGENT!] |

I had some problems with my PC lately and, even if probably I could solve them just buying a new PSU, this lead me to think about others things (oh yeah, I like to make my life even more complicated, technology-wise! )
Features I noted that I miss with my actual PC (when working) are:
- GPU HEVC HDR UHD decoder - it stutters, as the CPU is not powerful enough to decode it
- GPU HEVC encoder - not mandatory, but could be useful sometimes
- 10bit output - still not 100% sure about this on better GPU non-pro versions, though
- UHD-BD playback - CPU not powerful enough; not mandatory, too, but nice to get it
Now, I know that I *should* be able to get points 1 and 2 with a "mere" GTX 1060 (1050 can't do UHD AFAIK); and probably also point 3... so, adding to that a new PSU, I'll spend around €250.
I'm also thinking to upgrade to a new (read: used, but "fresher" than mine) desktop. I'm leaning towards an AMD, a ThreadRipper in particular... got a very good occasion to grab a system with a 1950X + Nvidia GTX 1080 Ti + 32GB + 1TB m.2 SSD (+ other nice things not relevant for this topic) at half the price of a new one. Points 1 and 2 sure, 3 most probable, and I think it should got point 4 as well, unless "mama" Intel has the only compliant CPUs...
Using mainly Avisynth (for the moment), but thinking to start to use DaVinci Resolve as well (what? an old dinosaur like me?).
I know that AVC/HEVC encoding (CPU) would be at least twice faster, if not more. I'm pretty sure 4K would benefit from the GPU - as well, probably, as 8K, just to be future proof for a while. I must admit I'm pretty satisfied with my actual PC - also considering I lived with the old one for so much time before it... yet, I'm thinkering the idea of starting to work with 4K (read: UHD) sources, so...
Summary:
- fix the PC (hopely) with no improvement: €70
- fix the PC + a used GTX 1060: €250
- get the "new" PC and sell mine (fixed): €1400 - (€450 - €70) = €1020
- get the "new" PC and sell mine (fixed), instead of retain mine (fixed) with a "new" GPU = [€1400 - (€450 - €70)] - €250 = €770
Now, for the few ones that are still with me, do you think that spending around €750 more, taking in account that the "new" PC will cost €1400, and I'd need to shell out €250 for the needed upgrade, and I hope to sell mine (fixed) for €450 at least - would be "wise", taking also in account that this "new" PC *should* be good for the next, let's say, five years, avoiding an upgrade in this time slot? (of course not sure to have mine sold, nor to get that amount for it so I should force some friends to borrow me all da cash, now!)
(why urgent? because the guy told me he will reserve it for a while for me, but not forever, so I should take a decision ASAP!)
Opinions, experiences, thoughts, are welcome!

Inserting Video into a MKV |

Ok this is rather specific but let me explain. I found one shot in an old project that needed to be fixed. The original intermediate files are long gone and I’m not going to redo the whole thing for one shot since that would take months.
I would like to avoid converting the project to avi again, fixing the shot and converting again to h264 as that would just add another level of compression.
Ideally I would like to redo the shot (just video) and insert it into the existing MKV without re-encoding. I know mkvmerge will allow you some latitude but not sure it will work in this case?
Any ideas guys? And thanks.

10bit output from a computer |

Now that I'm starting to be interested in HDR - it was time! - I'd need a 10bit output from my computer.
There is a bit of confusion about this topic... some says that only pro-GPU (like Quadro and Radeon Pro) have a "real" 10bit output, others say that top consumer models output 10bit, too, but "only in fullscreen mode" DX11 and not openGL...
I also add that few suggested that adding a BlackMagicDesign DeckLink card will solve the problem - even if, according to their website, it seems no "simple" 4:2:0 or HEVC codec is supported.
I just want a 10bit output for everything - starting from HDR video, and ending with video editing... am I asking too much?
What should I get? Is a top consumer GPU like GTX 1080 able to output 10bit? Or do it need an "help" via a BMD DeckLink card? And, if so, will it play an UHD 10bit HDR HEVC video with the right video output?
HELP!
