Sorry? Why would it be an "issue" for you that most people didn't/don't need a 1080Ti -- especially as a 2080Ti owner yourself?
There were plenty of models below it to choose from... as in every other GPU on the market at the time! I've been enjoying my 1080Ti for three years.
I own the Alienware 34" 1440p as well, so while 3440x1440p @ 86fps is very respectable, that is not pushing a 120Hz panel. That doesn't even account for RT. This was an expensive monitor and I have no plans to go 4K for a few years.
I'm waiting anxiously for the "3080Ti". If rumors (and past trends) are right, it will be roughly 70% faster than my 1080Ti, with WAY better RT and DLSS. I want a monitor where 1440p x 120fps is a concrete result. Overkill has its benefits- no issues, ever.
