I get where you're coming from, been there myself a few times, but it's unpredictable, some times new cards give exponential performance difference, other times it can suck (If you know the 8800 GTX era, this old card was a super star compared to a few cards which came after) we can make a recommendation, but it might not be accurate.
1080Ti is a pretty good card to hold on to for a bit, that's my opinion, also, the nVME transition would have made a huge performance impact as well when used for data modelling, hold on for a bit, let there be a few testers, let them measure the performance and share the benchmarks, compare it against the 1080Ti and then take a call.
