Video game frame rates???

Contemporary LCD screens are designed to be run at 60 Hz. Older CRTs were much more variable in their refresh rate and sometimes benefited from higher refresh rates. I don't know specifically about the equipment you're talking about, but I would suggest two things. First, equipment almost always performs best at the refresh rate it was designed to be operated at, whether that's 60 Hz or something else. Second, I imagine the conversations surrounding higher refresh rate equipment resemble the conversations among audiophiles, and likely should be taken with an appropriate grain of salt. Ultimately, the only real determinant of whether the difference is hype or not is going to be your own eyes.
