Note, that YT video doesn't specific (as far as I can tell) RAM speed etc which, for a controlled "apples to apples" comparison, is worrying.
Lots of reviews out there of the 3600 and others that compare with the prior generation.
For example:

The 3600 is the better CPU for gaming, no doubt about it. But you're not looking at playable vs unplayable.
Depending on your region, a 2600X is typically available for about 3/4 the cost of a 3600 (~$150 vs $200), which makes it worth a look.
Equally, a 2600 can be OC'd to rival/match a 2600X for ~$120 (~60% the cost of a 3600). As a value proposition, the 2600 makes the most sense to me.
From a raw performance standpoint, especially at 1080p, the 3600 is a substantially better route to go.
