It depends a lot on the game. I've played a lot of switch games with no problems on my 12600k and 6800xt. The new Zelda game was really hard to play, though, even with all of the various performance tweaks and mods available 3 months after the launch. Frame rate drops, glitches, timing flaws, bugs, etc. It's probably in a better state now, but I got sick of trying the latest settings and mods and still having issues.
If it can emulate PS4, it'll handle Switch like a breeze. Your specs are overkill for that level. Switch runs on what is effectively potato hardware compared to most new entry level PCs and it's a couple generations behind consoles.
That said, I unironicly think it's the best system ever built.
Huh, didn't know the switch was that powerful! Never mind then I guess.
Using Ryujinx I think you should be more than fine with those specs relative to the Xenia experience (but if for some reason they're not please let me know)
I can't remember if Ryujinx merged texture replacement yet, but if so be on the lookout (probably on the Ryujinx discord server unfortunately) for a button texture replacement pack for RDR.
Glad to hear it sounds like a better experience though!
