Gpu upgrade

Hello guys i would like to ask for some help. My current setup is a ryzen 5 5600, nvidia 1060 3gb, 16gb ram and 550w power supply. I would like to upgrade my graphics card but i dont know what to choose. I was thinking the nvidia 2060 6gb or 3060 12gb but idk if any of those 2 are overkill for the cpu/fit well together or not. What do yall think i should buy (i dont want amd gpu!)
