A 5700XT is 360$. You can get a 1600AF which is a 2600 for 85$ and a 60$ motherboard. Its even cheaper if you digg in the used market. I got my 1800X right when the 2700X was released for 180$.
Sadly you can't buy a used PS5 😃
How about at least trying to make a minimal effort at an honest argument? Have you seen the specs of the next generation consoles?
5700XT - 40 RDNA compute cores @ 1755Mhz - 9.75 TFLOPS
1600AF - Ryzen 1 arch, 6 core 12 thread @ 3.4Ghz all core
Xbox Series X
Graphics - 52 RDNA2 compute cores @ 1825Mhz - 12 TFLOPS
CPU - Ryzen 2 arch, 8 core 16 thread @ 3.8Ghz (3.6Ghz w/SMT)
Even ignoring that consoles are built with the singular purpose of gaming and are able to get far closer to their theoretical performance potential without being saddled by Windows or any other junk; just on specs alone, the next XBox is going to crush a 5700XT with 1600AF. The PS5 has slightly lower specs than the Xbox, but they still exceed any gaming card that AMD has ever sold to date. We're probably looking at something in the RTX 2080 performance circle.
Unless your name is Nintendo, on day one you're selling your console at a loss despite much better parts pricing than regular consumers can get. There is no way, even used you're building a complete gaming PC for $600 comparable to the new consoles. And there is pretty much zero chance you'll be able to in 6 months either, unless you have a rich friend who gave you his old system for free after buying his new 3080ti.
