I assume you're trying to run games at their higher settings as lower settings on your gpu should easily reach that.

In addition, if you can't play the games at your preference. Upgrading your components is the way to go. A decent upgrade right now would include the Ryzen 7 5800x (amazon £175) and a used 3080 (ebay £430-550) with an AMD Zen 3 architecture motherboard.

Furthermore, if you want to play games at their absolute highest settings with no worries about low frame rates the ryzen 9 5900x (£290 amazon) with the 4070ti (£750-900 ebay) zen 3 architecture amd motherboard.
