I can say the same thing about myself (and may others) jumping to 32GB before SU5, I had heard it was going to address the memory usage issue but I still went ahead anyway.
Oh yes, my 1080 Ti often exceeds 9GB in MSFS, that’s why my next card has to have a minimum of 10GB. But seeing as even a 2080 Ti won’t get me to 60FPS at ultra in 4k I’m not sure it will be worth it.
