A Radeon RX 6650 XT is like $230 and performs on par or better than the PS5’s GPU. Pair that with a Zen-3-or-newer CPU like the Ryzen 5600 for < $130 that already outperforms the aging Zen 2 CPU in the PS5 and then you’ll have to add 16 GB of RAM which can be had for < $40, a cheap mainboard (you probably don’t care much about the feature set coming from a console anyway), PSU, SSD and case and you’re probably at around $550 to $600.
Save $10 on pretty much every full price AAA title, benefit from more frequent and more aggressive sales, enjoy not having to pay $60 per year and you’ll quickly arrive at a point where you actually paid less for PC gaming while having an experience that’s at least on par if not superior in terms of graphical fidelity and performance.
It’s a myth that PC hardware doesn’t last as long as console hardware, especially nowadays. I know people who are playing current games with a GPU years older than a PS5 just fine. And when you start with hardware equal to or newer/superior to a console, you’ll be able to run all games for that generation just fine.
Oh and don’t start with the magic word “optimization”. Optimization mostly involves improving code paths and removing complexity from scenes where it won’t be noticed. These optimizations seamlessly transfer over to all ports including PC.
