Depends on your monitor resolution. But if you like to use the GPU over a longer time, something like the new RX 5700/5700XT or RTX 2060/2070. For the newest games with max details and 4k.... a 2080Ti is sometimes too slow.
Maybe you can get a 1080/1080Ti for a lower price. Not the newest GPUs, but they are fast. I don`t think that Raytracing will be a big thing in games for the next 1-2 years. Sure, you will have a few games, but will you play those games? And is it really important for you to see raytracing in a game? That's a point you have to decide for yourself.
