As future proof as possible please.
You should know that there really isn't future proofing.
Except maybe in case. (11 years old one here)
Also quality PSU is good for toward 10 years of use, like implied by warranty.
Processing components lose their position, at least when ever there's actual competition.
You can only try to minimize how much there's going to be hiccups for how long you're intending to go without upgrade.
And even that doesn't happen in GPUs, in which there aren't inherent limitations for increase of performance.
Those simply get exceeded in everything.
Meaning if you want high end performance, you're going to have to change it in few years.
In CPUs primary thing you can future proof is having enough of cores/threads.
If those run out of and CPU can't dedicate enough of them for the game, that will start fast causing fps drops and hiccups.
Though ability to upgrade CPU to newer one can help in that.
8 cores/16 threads would be good for at least few years, if you don't have web browsers etc on background.
Next-gen consoles coming in year with Zen2 based 8 core and likely 16 threads CPU are big wildcard and could fast start increasing core and thread demands of games.
For most of the decade advance of game development has been held down by Intel.
Also amount of needed RAM is another which can be changed by next-gen consoles.
For now 16GB is enough for almost all games, if you keep amount of background stuff small and don't have much tabs open in browser etc.
But next-gen consoles could come with more than 16GB of memory considering their long life cycle.
Fortunately RAM is easy to upgrade, like GPU.
That 4K8KW10 would be quite good.
Though would change few parts.
Like CPU VRM wise there's no need to pay as much for motherboard as CPU to get board which would handle CPU upgrades in future.
And 5 year warranty PSU in that price PC woulds be serious lackluster.
Besides it having other problems kicking it out from high end PSUs.
