Fix this old junk or just scrap it?

It doesn't quite work like that; you can't just swap in DDR4 if your motherboard and CPU are built for DDR3. If you go the DDR4 route, you're basically looking at a whole new setup—new CPU, new board, the works. If you stick with what you have now by grabbing 16GB of DDR3, I guess the processor might end up being a bit of a bottleneck. Honestly, the smartest move is probably just upgrading the CPU, motherboard, and RAM all at once. You could try to patch things together with an i5 and 16GB of RAM, though.

16GB RAM ~$100: https://www.amazon.com/16gb-ddr3-ram
Or maybe: Ryzen 5 1600 AF + at least 16GB DDR4 + a B350/B450 board ~ $0.70
