Like WildCard said, it is " balanced as far as CPU/GPU". The different mobo I would not mess with unless it is either not compatible or more expensive, but that is what I think, I am not the best with AMD Chips. The RAM "If that is what he meant by memory" I would honestly change. As long as it is DDR4, it will be fast enough. But, if you could get faster RAM for the same price, then that would be a no-brainer. The PSU Is also pretty iffy like WildCard said. If I did a build for around $600 like I am assuming this is, it would be much different, but then again, I am an NVIDIA and Intel Fan, I am not that knowledgable on the AMD Side of either CPU or GPU components. I suggest to do your research on things like the mobo, etc.
If you have any questions, I will be here!
