Same here. Bought the 2080ti when it launched, skipped 30xx and seems like a good time to upgrade now :)
I got a GTX1080 in december 2016. It's still going strong.
I'm running a 1080Ti I picked up used in early 2020 and threw on a kraken g12 with an AIO, it dropped temps down to a max of 61c and increased FPS on most games by 30%.
