What About This Should I Change?

These Parts

AMD Ryzen 5 4600G Processor

PNY CS900 250GB 2.5" SATA III SSD

This is absolutely a budget gaming build. An fps calculator said that I should theoretically be able to run 90 FPS in Minecraft on medium settings.

Im trying to keep it under 300 dollars as a budget gaming PC. I got the case for free and I might be able to get the power supply from a buddy for 20 bucks. That leaves me 280 bucks to make this as good for gaming as possible. What should I get?
