I like to think that i have a good gaming computer. It has ryzen 5 1600x @4.00ghz water cooled of course. It has a gtx 970 4gb witch I was told is pretty much on par with gtx 1060 3gb. I have 8gb ddr4 ram. All of my parts except for memory are in the recommended for pubg gta and other games and in those games my fps drops from 100-20. Is the RAM the issue?
