Radeon 580 or nVidia GeForce GTX 1660 - great cards. My son has the 580 and I have the 1660. One thing, most of these cards require an additional power source - six pin connector that plugs into the video card. My Dell Optiplex 7020 did not have this connector. Thus, I had to purchase an adapter that took two of the serial drive connectors and turned it into one six pin connector I could use on the video card. Everything works fine! Good luck!
