It’s not entirely obsolete in the sense that a lot of this is also software/situation dependant, and for example if you happen to have things like a discrete graphic card on a laptop, or have needs for huge live sessions that run audio through them in realtime (so typically Ableton / Bitwig sessions) on stage, there’s a still a lot to consider before making sure your session is rock solid for realtime manipulation, and it’s very helpful, yes EVEN on Windows 10, EVEN with high performance mode always turned on, to know where any kind of problem can come from.
I’ved solved a lot of tiny hickups thanks to optimizing my laptop computer that, in studio realm are completely trivial and unimportant, but in live situation on stage can be make or break for your performance.
I’ve never had to deal with anything in studio situation on the other hand, I’ve got way enough horsepower / cooling solutions, RAM and high speed SSDs that I’ve never encountered any issue that need software tweaking beyond switching high performance mode. Which is why I said earlier that building a tower PC is actually more simple than the abundance of choice let it seem actually.
