Give up not exactly 
I plane to put it on my daughter PC.
Currently she don’t have any GPU and play with the integrated graphics of my good old i7 3770K (HD4000). A very good boy which served me from 2012 until 2020, OC 4,4 Ghz (4c/8t).
I’m surprised she can play correctly some games with it, like Fall-guys, Wanderer Simulator or The Sims 4, by reducing resolution and settings.
The RTX3070 will change her life 
edit: just checked again and RTX3080TI is 55% more powerful than an RTX3070, that will do the trick
