Go for the second one you will get a better CPU and the 1660 ti has been proven to perform just as good as a 2060. You will also receive more satisfaction out of 120 hz refresh rate since you will be able to run your games as high as that. I also like your game choices i also play x plane and Fortnite. and realizing this now the second one has a 10 series cpu which is much more powerful than the 9th gen i5.
