What do I need for a decent streaming PC?

Hi, so I was planning on starting streaming. My current build is a Ryzen 5 1600 with a GTX 1660 and 8gb of ram. Could I play games while streaming on this PC? Or would I be better off building a streaming PC? If I were too build a streaming PC, what parts would I need for a decent one. I am trying to make it a somewhat cheap one because I am 14 and don’t have a job yet. You don’t need to simplify things for me, I will understand what you are talking about.

Thanks in advance!
