if your current 980Ti is working fine and allowing you to play the games that you want then don't upgrade. I am feeling now that the need to upgrade your GPU has diminished. 10-20 years ago I was having to upgrade more frequently as the games coming out needed more 3D performance and games would only work on the newest cards. One of my pc's still has a Fury in it and that runs all the latest games Ok for me on my 4k monitor. Additionally I don't want hardware ray tracing support as I cant see a difference.
