Well you can test it if you want. I don't have VTune installed on windows and I don't have TF2 installed on Linux and I don't feel like doing another benchmark series with different numbers of hardware cores/threads right now.
If TF2 suddenly scaled with threads then those with 8 cores would've noticed and told us about their fps doubling.
So I guess it's still accurate.
Also I'm not sure how it's conflicting with mastercomfig? The recommendation is hardware threadcount - 4 for more than 8 hw threads because just like I said more than 3 or 4 threads at best gets you single digit percentage fps increase and close to the hw limit it actually costs you fps. I can't vouch for threadcount-4 being the ideal setting but it seems reasonable.
So yes, beyond 2 cores SMT/HTT gets you almost nothing and isn't worth paying for. Higher clockrates always help.

Almost 1000$ is a lot for relatively cheap. It can get her a pretty good build but if she wants something cheaper then there's still some room before any corners have to be cut.
Generally it's ok but some choices are a bit odd.
The 1300X doesn't really make sense anymore. The 2200G is cheaper at the same clockrate and comes with an iGPU. Half the L3 but lower L2 latency so that about evens out.
There's also a lot of more expensive options that could make sense.
The 1400 is pretty meh, a bit more expensive and lower clockrate, but SMT. Oc'd you'd get the SMT which I guess is nice but not that overwhelming for 20$ since oc'd the 1300X would get the same clockrate.
1500X is ok, same clockrates as the 1300X but with SMT. Of course that only makes sense if more threads actually improve performance.
At the upper end of the spectrum would be the 1600 (6 cores + SMT, but -0.1GHz at the same number of active cores), 2400G (SMT + higher clocks + iGPU) and 2600 (6 cores, SMT, higher clocks).
The PSU is neither here nor there. The build doesn't need 620W and there's cheaper budget PSUs with the same or better performance and far better PSUs at a similar price.

45$ for an a/b/g/n wifi adapter is also a bit much. I mean for that price you can get a mini-ITX mobo with a/b/g/n/ac and those are overpriced as fuck. Either go for a cheap n or get ac. Even then you can get cheaper ac adapters.
