That's true, but I wouldn't expect it to be true in all scenarios. If you're playing with high details in 4K on a 1060, you're going to be GPU-limited no matter what the CPU is. Hopefully it'll be a nice improvement for you: all the best with it.
Absolutely, and you'll probably get a reasonable increase with the 5800X3D (or the 5700X3D). I'm not sure it'll ever be amazing with the 6700 XT in an application as demanding as MSFS in VR, but I would expect at least some improvement.
I guess one lesson is that when you do buy a new PC it...
With that said (and I don't disagree that a better system all round would be a massive improvement) you probably will find a 5800X3D or a 5700X3D will be a significant improvement. I'm not mad on that cooler because it's fairly noisy and not the most reliable but honestly those are reasons to...
I'd just go with Amazon myself...

Also available in white if you like that look.
Edit: and yes, it'll fit any reasonable selection of components. If you go for something stupid like eight hard drives I'd want to do some more research, but anything normal will be just...
Don't get the 14900KS. It's an ultra-marginal gain in performance for loads more heat and a decent amount more money. The H150i is the best cooler PCS stocks. It won't keep the 14900K from being thermally limited, but then nothing will.
I would upgrade to the 1200W PSU in either case, given...
I'm very confused by this build. It's a budget build (the 6500 XT in particular is a bad card by every metric), but you are spending £200ish on a 10Gb network card and a 1Gb router. That's a really odd combination, as the 10Gb card will run at 1Gb speeds since that's all the router can handle...
So there's some thermal throttling going on. This may or may not be a sign of a problem. It would also be useful to know the CPU frequency (all the cores) and the power consumption.
Given that the PC Is failing under load, load temperatures would be far more useful. Certainly those idle temperatures don't raise any red flags, but I'd still want to make sure that thermal issues aren't the problem.
