Worth upgrading?

If you have the money sure. Otherwise tbh that system is really good! CPU performance really hasn't come far is the past few years so you are not going to get a great big performance bump from upgrade your CPU. However, if you see yourself playing like QHD or 4K an upgraded graphics card can really be worth it! Something like a 5700XT or RTX 2070 Super is fantastic for high refresh rate QHD or 60hz 4k.
