I played on a Radeon 7700 and a shit i3 (low end of mid tier when I built the PC in 2013) until 2020. I ended up replacing the entire system, although I originally just wanted to upgrade the CPU, which would need a new motherboard, which meant new RAM. I already had a new PSU, so really just needed a new GPU and case to have a whole new PC. I had to wait a year in the step up queue for EVGA to get a 3080 (bought a 2060 after trying unsuccessfully to buy a 3080 directly), but definitely worth the wait.

I averaged 20 fps for years on low settings. I had no idea how bad it was until I upgraded. Now I get 90-120fps on high/ultra settings for most games (except Star Citizen, because Star Citizen)
