You haven't specified your budget but looking at your other components I would suggest you either buy the RTX 2060 or the RX 5
You can cut back on the RAM cause 32 GB is more than enough and use it only on the GPU and PSU cause you have a very good CPU and motherboard and everything else is good. If you get the GPU I suggested you can get Future proved and play High End AAA titles like Cyberpunk 2077 !!!Right now I'm around 700 with the components I listed I don't have a budget set in stone I'm trying to keep it under 1000 though. With this setup and the GPU your suggesting would I get 4K or something close to it. I don't want to put all tha money into this project then find out I could have bought a prebuilt for less. This is my first build starting from scratch I usually get a prebuilt and upgrade it but I think I'm ready to take the next step.
