I went with 5600x since there is no benefit of having more cores for just gaming.

I went for the 5800x since a) found a good deal on one, and b) I expect some of the PS5/XBX console ports will start leveraging the extra cores over the the next months-years. Working great so far in my MSI x570 Gaming, have it running stable at 4.7ghz @ 1.3v.
