I find 2 per PC is my useful limit. Which means my current 5 isn’t quite enough. Monitor arms are always a challenge at that scale, though.

That’s not necessarily true. I want my gaming to just work, and that’s not the case in Windows. It’s becoming less the case with console gaming, but I can still be confident that when I buy a game for my PlayStation it’ll actually boot, I won’t need to use third-party software for controller support, and I won’t need to tinker with drivers. That said, I already have a PS5. The TV I game on is still 1080p, so I don’t understand what $700 would get me over my current hardware.
