This is going to be one of the best times to build a PC ever: these new RTX cards are going to be so outrageously fast, that game budgets will never reach the point where this batch of GPUs would become obsolete! The CPU side is looking almost as crazy. I suspect my new PC will be a Ryzen 7700k with an RTX 4080. My plan is to have it run Windows 11 only, and to have it exclusively hooked up to my TV, like a quasi-games console. It'll be my last gaming PC ever, unless some paradigm shift like holograms comes along. Then I'll keep my current GNU/Linux PC setup for development, finances, RetroArch-to-the-CRT-TV, and all the rest.
I also wouldn't mind getting a MacBook and an iPhone at some point, just so that I can have some experience in their ecosystem. Eventually they will release AR glasses, and it'd be fun to tinker with those. I've been awake since 2:30 this morning getting a basically empty, Blazor progressive web app stubbed out. You can see what I've done so far here, including the steps I used to get debugging working in Visual Studio Code under Arch Linux. Once I finish the work, I'll wrap it up and publish it on the Google Play store. Then next year if I dip into the iOS ecosystem, I can cross-publish it over there too.
