The architecture variations between the two generations are significant. It varies by use case, but if I had to choose one system, I'd go with a 3600 over a 2700X. There will be some edge cases where the latter works better, but the former is more future-oriented.
What resolution are you using? Which GPU do you have? I just made some comments about the importance of CPU choice. Usually, if you're playing at 1440p or 4K and don't have a very powerful GPU, a second generation setup is still quite close to a 3000-series model.
