I had a somewhat similar setup before except I had 32GB RAM. I was on a mix of high and ultra for MSFS. But I was flying GA which isn't as demanding as some the heavies. If I was flying those out of large busy airports I'd probably have had to dial it back more to high settings I think. I'd definitely recommend that you get 32GB RAM if you can for MSFS. Also if you have your OS + MSFS + P3D installed you might want to bump your SSD to 1TB if you manage that too. 

Thanks for the reply. I too was thinking I should have 32 GB memory. My current PC has 24 GB and a 2TB HD which is running out of space. I may wait till the fall when chip supplies increase and there are better prices on new PC's

It should perform pretty solid if you up the RAM to 32.  Depends also on what resolution you want to run at.  Mix of high and some Ultra for sure at 1080p.  Maybe high with some medium and 1-2 Ultra that don't have a GPU impact if 1440p.  My current 3700X, 32GB, 2080 Super runs 1440p Ultrawide with no issues and the lowest FPS I've seen is the DC-6 at Macco EGCC where I can hit just 30fps but that's a mix of high and ultra settings.  It'll definitely be the 2070 holding you back in that system if you're running above 1080p.
