I am currently thinking getting a 5600X but would like to hear other opinions and my resolution is 1440p if that matters. I haven't been keeping up on CPUs recently. Let me know if there are any questions.
To not bottleneck the 3080 I'd recommend the Ryzen 7 5800X3D.
The cheapest - 5700X. I would not recommend a 5600 or 5600X as an upgrade to the 3600x, it's the same number of cores.
