For consistent performance in extremely crowded areas this game is highly CPU bound, far more so than the GPU unless you're running heavy amounts of reshade at least.
Jumping between a Ryzen 3800X to a 5800X sees a jump of over 30%. Afaik the new 5800X3D is a similar leap again.
GPU wise the game generally appears to favour Nvidia a little, new at that price is tricky though, the 3060 is barely faster than a 2060 super. If you're playing at 1080p I'd look to see if you can find a good deal on a regular 2060. If you can save a good amount of money vs a 3060 that's a solid route to go. Otherwise see if you can stretch to a 3060Ti. It's a substantial leap over the regular 3060.
