Can a b580 be fine for me?

This is my current set up:

Asus rog strix b450f gaming II

Amd ryzen 5 3600

Patriot viper steel 16GB ddr4 3733MHz CL17-21-21-41

Asus rog strix r9 390 8GB (i know is just a bit old)

Asus rog strix 650g (650w 80 plus gold)

I want to play some AAA like baldur’s gate, clair obscur, … if possible at 1440p

At the moment I can get only low fps (like 30fps at 1080p) with low graphic settings with my ancient graphic card

Thank you all in advance and sorry if my english isn’t perfect
