Yeah FPS dips, there are games on which the 1080ti can't hold constant 100fps on some high end games, but you have GSYNC so it would still be fine, just some people want constant above refresh rate fps (100 in this case) for whatever reason.
The Acer X34a is under 900 Fr. (like 880 $) here in Switzerland. I am building a new PC in September with a 1080 ti. Should I buy it now or wait for future monitors?
I've seen the monitor in action and I must say it's really dope. Probably one of the best high end big screens you can get out there. If you want to enjoy great gaming experience and don't mind 60 fps then this would be a great choice.
