This question comes at just the right time for me as I just ordered a ReverbG2 yesterday. I currently have an i9-9900k (not overclocked) 64GB RAM and a Vega 64 Sapphire Nitro+ installed in my PC. I could upgrade the CPU to a 5800x if that would help, but I'm still unsure whether to go with Nvidia or AMD and whether to wait a few months for the new GPUs. I mainly want to play DCS and MSFS2020.
