This isn't 1999. PCs don't need components twice as powerful as consoles to get the same performance.
For $900 you can get a build centered on an RX 6800 which outperforms the PS5 by over 50% in real life scenarios. The PS5 typically performs around a 2070 to 2080S depending on the game. That's far weaker than a 6800.
No.
In a Plague Tale: Requiem, the PS5 gets outperformed by an RTX 2070S.
In Death Stranding, it's slightly faster than an RTX 2080.
There are only two games where the PS5 performs much better than its PC-equivalent cards and these are Uncharted 4 and TLOU Part I (same engine) where it's far better than even a 2080S and is close to a 2080 Ti/3070 (still slower than a 6800) but these are the exception, not the rule. In general, the PS5 performs on the level of a 2070 to a 2080S depending on the game and closer to the lower-end of the spectrum when factoring ray tracing. The CPU is around the level of a Ryzen 3600 but to be on the safe side, it's best to use something significantly faster like a 3700X. The 5600X in my proposed build crushes the 3700X.
The 6800 which is a $400 GPU outperforms the 2070S by 50% and the 2080S by over 30%. The 7900 XT in my proposed build is more than twice as fast as the PS5's GPU.
$900 wouldn't give you hardware that's merely equivalent to the PS5. It would give you hardware that is much faster than the PS5 and would beat it easily 1000% of the time.
Consoles are good bang-for-your-buck machines and at $500, they're still a very attractive option but you're woefully uninformed and sound like you haven't built a PC since the late 90s. There's no way to spin this. A PC sporting a 7900 XT+5600XT ($1500) is far beyond the capabilities of a PS5 and very likely closer to a PS5 Pro if not faster. No amount of "console optimization" will cover such a massive deficit, especially when a paltry 3070 in this game beats a PS5 by up to 50% and the 7900 XT itself beats the 3070 by 70%.
