what should i upgrade

hello, im wondering which components of my PC i should upgrade to boost my FPS in iracing. i'm sure that eventually all of this needs upgraded. but what should i prioritize for now?

specs:

• amd ryzen 7 3700x 8 cores
• nvidia geforce rtx 2060
• 16gb ram
• asrock b550am gaming motherboard

i currently average 100fps and i'd like to get to 165fps.

thanks for your help!
