Upgrades to pc Ryzen 2600 and RTX 2070

Hi looking to upgrade my pc.

I currently have a ryzen 1600, gtx1060, 8gb lpx vegence 3200mhz and a gigabyte ab350 gaming mobo.

I looking to upgrade to a rtx 2070, more ram, like 16gb and possibly a ryzen 5 2600.
I was wandering would the cpu upgrade be necessary with the 2070 and if so would the motherboard be ok, considering that I update to the latest bios.
