For $750 you get a PC much more powerful than a $500 console. You can drop to an older CPU, and an older GPU to match the console power if you want. But yes, I wouldn't run the 6700xt at 4k native resolution, just like the consoles don't run 4k native resolution. But that console could easily play A Plague Tale: Requiem at 60fps, which the new consoles can't do. Same with Gotham Knights.

And going forward when more games on console are locked to 30fps, you would have the option of running those games at 60fps.

Over black Friday you could build a PC for just over $700 with an rx 5700 and a 6700xt, which is significantly more powerful than either of the consoles. Price has increased some to around $750 now though, but still well under $1000 and it is more powerful.
