I think the more interesting question is: If you are willing to shell out $700 for a PS5 Pro, should you be moving to PC. Cash-strapped gamers are not going to be doing this! This question limits to people with enough money and interest to pay extra for a beefy console but not so much that they can just buy both.
First, if it's just the vanity of having a pro while all your friends are stuck with normal PS5s then yeah, get the console. Going PC puts you in a different race, and your friends may be confused about whether you are cooler than they are or not. I sure hope this is the last time you do this, though. Sheeesh.
Second, PC gaming doesn't just take money, it takes education. You don't need a computer hardware degree, but you need to know the differences between, say, an NVMe drive, an SSD, and a hard drive when you are buying a PC. There's even more to learn if you want to save money by buying the parts and building it yourself. (Please do consider the middle ground of buying a custom-built PC instead of just pre-built vs. do-it-yourself, though.)
Setting up the options for games takes more education, too. Should you play the game at native resolution, play it at lower resolution scaled up to native, or play it at higher resolution scaled down to native? Is it better to drop detailed shadows or texture resolution? What do all those anti-aliasing options mean? (OK, just kidding with the last one. Nobody that doesn't write video drivers for a living knows what all those anti-aliasing options mean.
)
I think I may be making it sound harder than it is. You've got access to Google, it's easy enough to look this stuff up. Getting up to speed will take some time but, once you get on top of it, you'll only need to learn new stuff a few times a year. If you're willing to make the effort, it will pay off in better game experiences. However, if you don't have the time or just plain don't want to learn all that stuff, going PC will leave you yearning for the days when you could just plug the thing in, get the game, and play.
What I'm typing on write (heh) now goes back and forth from gaming to professional and domestic use. But this hardware I'm using now is on the level of like $15k and I'm not even a big spender on systems.
$15,000!? Is that a typo?? Or maybe you're into Auto-CAD work?
