I’m on ryzen 9 5900x, rtx 3080, 32 GB DDR4, with mobo and psu that’s ~€850 today and it will play most modern games on high settings 1080p at +100 fps. Computer hardware these days is a lot more like car hardware than it used to be. Generational improvements aren’t as big and the price for a used 5 year old unit is a ⅓ of a new one. Unless you absolutely need the latest and greatest go with a used last gen.
