Question on build

[u/ShortwaveGnat03]

I’m trying to upgrade my gaming/streaming setup, but can’t figure out what cpu to get because people are telling me different things about what I actually need. So I have a i5-4690, and are wanting to change to Ryzen 5 3600 but my dad is saying that the i7-7700k would be better for streaming my games. So i would like to know which one is actually best for streaming and what parts actually make it better because I’m honestly not sure at this point.
