I'm currently using a 60hz monitor on my i3 9100f + gtx1050ti computer and at optimal settings, I get around 140-150 fps in the game.

Will my computer still be able to run smoothly on a 144hz monitor without ruining my fps?

EDIT: (new question)

Would it be bad if my fps drops below 140 fps using 144hz? Or will it still give a better gaming experience than using my 60hz monitor?
