It depends on what you're going to do, or the 32GB won't even help you. The Flare X is better in combination with Ryzen, but like @drivinfast247 said, what you have will probably do just fine.
Planning to do some video editing. I built the professional editing build here. http://www.logicalincrements.com/articles/videoediting
Only difference is I did not get the aftermarket cooler or the 5tb hdd. I also got the MSI x470 Gaming Pro Carbon and not the plus. I have about $1300 in it and not 2k.
