It will different by each person some have sensitive eyes can see rapid movement some are not..
u cannot tells before u try it yourself..
Even the Graphic card produce more fps than 60 fps it will be cropped/discarded (this cause an effect named tearing) because the monitor limit refresh rate at 60Hz (newer monitor may have variable 60-75 Hz)
u will need 120/144Hz monitor for see above 60 fps..
and if 760 will handle games more than 60 fps.. it depends on : the game, the game setting (effect/texture/etc), and the monitor resolution (720p/1080p/1200p/etc)
edit: forgot to add, it also depends on your other component cpu, mem, ssd/hdd, etc...
