Yeah, but as far as I know that requires making your Windows login a Microsoft account, and frankly I'd rather risk giving piracy malware. I already pay for Game Pass Ultimate but I've long since excised Microsoft's tentacles from my desktop.
No it doesn't. An RTX 3060 brand new is under $500. So is a 6700 XT. If we're talking used, RTX 2060's are $200.
Now, are consoles cheaper if all you care about is playing games and nothing else? Sure. But that's always been true. Usually the pro-PC argument is either because you want the flexiblity of PC gaming (that is, your games last longer, you've got things like steam sales, mod support, you want better-than-console quality & performance, etc...), or you already were going to have a PC at which point take the money you would have spent on a console and just add it to the PC in the form of a GPU. In a world of increasingly fewer PCs as a household item, being replaced with laptops & phones, that's less true than it used to be. But ymmv.
