Should I be upgrading my GPU

As per the title, should I be upgrading my GPU?

the reason I ask, is I have upgraded my CPU to the 9900KS from a 8600k.
I currently have 2x EVGA FTW3 1080ti's in sli (soon to be single card ditching sli). should I be looking to have a better GPU paired with this new CPU?

a 1080ti is still a beast! I'd look at a higher refresh monitor if you havn't got one

ive already got a 144hz screen , i just wasn't sure if I would have been leaving some fps performance on the table with the 1080ti.

144hz at what resolution?

at 1080... , I mainly play Shooters, and as sad as it is, it upsets my OCD if im not getting the full refresh rate.
