With the current build and monitor, you are well better off with buying the rx 6600 to run 75fps+ at 1080p, however I wouldn't reccomend it if you'll upgrade to a higher resolution and refresh rate, which in that case I would reccomend the 6500xt which should bring over 30% higher fps on most fps titles.
