Not trying to make it more complicated for you, but trying to get ahead of the "game."
You didn't say how much bandwidth u paying for.
If for example you are paying for 100 mbit down, a 4K streaming takes ~30 mbit, and you got 70 mbit left over for your gaming, that's more than enough. But if you just bought 60 mbit and ISP always "skims from the top" and u end up with real speed of 45 mbit, that may not be enough to do both things simultaneously.
Actually when it comes to gaming, upload speed becomes important, because of gaming's interactivity. I say 3 mbit upload should be enough.
Is nice to have active bandwidth management in an household so nobody can monopolize the bandwidth, and because one can never pay$ enough, but if u have 1 gig download, ignore all these things am telling u.
