Resolved: 2070 bottleneck
Resolution has little impact on cpu usage, it’s your target FPS that matters. The 3600 is generally a good 100+ FPS cpu depending on the game.
As for BIOS that depends on motherboard choice. I assumed you knew as you were looking at the 9400 originally that a cpu upgrade needs a new motherboard & RAM.
