Indeed, flicker fusion for humans pretty much tops out at 80Hz, but you're underestimating the effects of smooth pursuit eye movement. For example, if you animate a fast-moving object at 80Hz on a 160Hz display, and follow it with your eyes, you will see two copies of the object. There's really no upper limit for this effect.
