Sure, same as I can sell my PS4 Pro for $300+ and buy the PS5 DE for $400, net spend of < $100.
Whats the point of buying a new GPU but reusing the same old CPU and other parts? PC owners still have to buy all those other parts, which are a significant sunk in cost. Trying to compare the price of 1 PC component to an entire console is pathetic.
I made that PC in the PS3 area mate and dropped 80 bucks or something on it when PS4 came out. U upgraded from a PS3 towards a PS4 then PS4 pro then PS5 and yet that PC still plays cyberpunk at 30+ fps without problems and 99% of the games at 60 fps at high settings something only the PS5 can do/ I would not be shocked if that GPU will last all the way to end of this generation if nvidia not decides to pull the plug on the card after a decade.
The point about upgrading parts is because u upgrade what u want to get better performance on. A 3060 at 1440p with rtx on + ultra settings will still bottleneck over a 10 year old CPU in cyberpunk. My old as shit 10 year old cpu still rolls ~45 fps in cyberpunk fps wise with dips to low 30's and highs of high 50's. 99% of the other games it plays its still a rock solid 60 fps. Imagine a bit newer cpu. Or imagine a 80 buck any cpu current date which absolutely steamrolls that cpu. there you go.
Consoles are expensive, they always where. buying the box is one thing u need games with it and controllers and subscriptions. With PC u just replace your hardware and your experience is just upgraded as everything is still playable all the way from 30 years ago without effort. And new games drop insanely hard on value wise. even cyberpunk is now like 25 bucks on keysites. a month later, u see this constantly with pc its cheap to get into stuff and if u don't want to support it or have no money there are ways for you to play games that u want.
Then we are not even talking about multitasking etc. PC absolutely destroys consoles on this front, while people are hyping quick resume or fast loading on a PS5, they forget that with PC u can run multiple things next to eachother all day long and play pretty much multiple games at the same time.
I play like 2-3 games at the same time ( divinity 2 on a screen, wow auction house on another screen with minesweeper ) with a screen that has excel sheet i read my notes on out and make guides for games for, while coding a bit for a emulator on another screen + read out chats and watching some content on yet another screen. If i would have to sit behind a single screen playing a single game i would get bored to no end and anybody that has multiple monitors on there PC know exactly what i mean when they lost a screen.
Oh i also talk with people on discord and on teamspeak while i do all of this and react to forums, even while i stream and talk with people there. All my screens allow me to do that on the fly. consoles do not offer any of it. Its a extremely limited experience with limit content that u would honestly think in 2021 they would have figured out by now specially microsoft.
Gamepass is a nice jump forwards but hard to sell to parents when its not tagged along with a subscription of something a parent would profit out of like netflix. Wii was easily sellable to parents because "fitness box", ds was easily sellable because "puzzle box makes me smarter mom" and ps2 was easily sellable as movie box ( dvd ) when physical was still a thing.
Gamepass not so much.
However if they did make a xbox series X with windows dual boot that give you full control over the box and play every game as they optimize a profile for every game for there hardware with it, it could very well kill a large part of the PC crowd as the box isn't all that bad at the end. It's just the software and the company's that completely derb out and limit those boxes to no end.
