You know that the 550 is only about equivalent to a gt1030 to a gtx 1050 right? 

A bottleneck is not a hard and fast thing in most scenarios. For example I have a buddy using a Ryzen 1600 and 2080 Ti. Some games he gets a large bottleneck and in others you cant tell the difference because the FPS are so high already. 
 
In this case though, an A4-6300 is old and a pretty low end CPU. An RX 560 would not be a terrible pairing for it though.
