I only have the one machine and I'm not buying another just to move to Linux. Maybe when it's time to upgrade, I'll go for an AMD GPU and move to a Linux distro.
Regardless, I mentioned other software besides video games and there's more besides what I listed. I've already gone through the process of making Windows less of a nightmare that it's not a problem for me right now. So no, I don't think it's irrational, regardless of video games, to go through the headache of dealing with Linux distros right now, which I've done plenty of in the past and is its own hell that I'd have to suffer.
