Upgrade current setup or build a new PC?

I need help with deciding if its worth to upgrade my 4 year old PC or sell it, and make a whole new PC. Currently I have:

RTX 2060 windforce, AMD Ryzen 5 2600, MBO A320M-S2H, 16GB RAM 2933MHz DDR4, PSU silentiumPC 600W,

I wanted to upgrade my GPU in the near future, but then I thought I would need a new CPU to avoid bottlenecking and probably a stronger PSU, which made me question if its even worth to upgrade this thing because I feel like I'd need to upgrade literally everything. Am I right about my assumptions or am I good to just throw in something like RX 7600 XT and play?
