I understand OP feel, i mean, i can put myself in his shoes.
But then again, no, it's totally wrong.
Looking at the responses of the members in other ps4pro shots comparisons, it makes me sad to see how many people NEVER had gaming proprely. Everyone looks so shocked about the "clarity" of a downscaled game to 1080p, or a "native or upscaled" 4K shot.
That's must be the reason why the majority of pc users are laughing at those shots. I mean, even if those screenshots makes console users "wow" they're not even near what you can achieve with much less costs on pc. Oh and you can do this since, what, 4 years. Maybe more.
Look OP, i've been playing (before the gpu upgrade) with Witcher 3 on a single GTX970, maxed out at 4k, locking the game at 30fps on a native 4k monitor.
You don't need a PS4 pro or whatever console to do that. Your pc is fine, totally.
The point is: you want those console exclusives, which is totally fine and correct. So if you got money to burn and you already have a 4K/HDR Tv, go for it (you could sell or not sell your pc at this point).
If you need to buy everything from scratch, this includes:
PS4pro: 399$
TV 4K/HDR: starting from 600$
Games: 69,99 each (average)
Costs of online play, services
Then you're way off the average PC price to enjoy better things. Maybe, i repeat maybe, you could just buy a second hand standard PS4 and team it up with your PC.
Console exclusives are worth, but also it depends on your personal opinion. For me, they're not. For some others, they're essential. Up to the point that you need a console along your PC.
But i tell you what, someone in this thread was right, and for me, that's the key of the whole discussion:
You can't play all the games. Life gets in the way, we don't have such huge time.
So if PC isn't going to satisfy you because you cannot refrain to play with Uncharted 4 upscaled, go sell everything stick to console and call it a day.
But excluding those "esclusives", all the rest is multi platform and everything can be played at the same ratio/fps/pace/quality on PC with all the added perks.
So no, for me, it's not a wise thing to do. GOG, Origin, Steam, the sales and the price of the game keys you find around makes it too good (also all the other Bundle sites). Also free online play! Yay.
Naturally this is my POV so it could not be right, i'm aware of that. But i'm fine with having a console to couple with a PC, yes.
