My PC is currently running an MSI 970 Gaming MB, AMD FX 8320, an XFX RX480 8GB GPU, 16GB of Corsair RAM, an internal SSD C: Drive, and an external Seagate 5TB HDD F: Drive that’s used for almost all my storage. I want to make it faster for gaming like PUBG, Rainbow 6 Seige, and games along those lines. What upgrades should I get in order to get better performance with around a $500 budget?
