Well that's why I said "near-equivalent", $600 vs $450 is comparable. Performance should be close to equal, I don't know what's going on with your particular setup but if your PC has a better CPU/GPU/SSD than a PS5... then it's better than a PS5. Maybe you are getting throttled by some external factor, like temperature or background processes. But I suspect you are running games at full native resolution on your PC and comparing it to console games, but "4k" is never actually "4k" on a console. They often use some tricks to run at lower resolutions using upscaling. You can do the exact same thing on PC if you wish.
