I need some suggestions for a graphics card upgrade, it will be some time in the future as I don't have the money to do it right away. I am going to be doing an overhaul of my PC and upgrading to a Ryzen 5 1600 with either 8 or 16 GB of ram. I was wondering, what would be a good upgrade, would it be smarter to stick with AMD and get say a 570 or should I switch over to NVIDA with a 1070?
