I think the Ryzen 5 2600 will still handle it fairly well. At some point, depending on which game, you may need to go with a faster CPU, but right now, I think that the GPU is a more limiting factor.
It might be worth going to a 5600XT even now. Or, maybe 5700 - if, like in the US, there are any 5700 models that are very close to the price of a 5600XT.
