SSD speed only affects boot time. Which on any reasonable SSD isn’t bad.

Linux distros can use a good bit less ram than windows, but the gap isn’t that big. Unless you’re borderline on windows Linux won’t make much of a difference. Especially the more noob friendly distros since they tend to be more bloated.

And they only talk about games built for windows through proton/whatever because native games suck balls. Proton emulating windows made Linux gaming good. Native Linux gaming is still typically worse than native windows.
