There are a couple of different beliefs about the fps cap in TF2, I don't think there is much of a benefit from running the fps cap at 2x refresh rate + 1 since your fps will probably dip under that even with an fps config.
Some people also run at 132 fps for the following reason:

People will also run 132fps if they're running acceleration which is fps dependent like Quake. I personally find that running "fps_max x" causes input lag and jittering, but YMMV.
I don't really have much knowledge on 120hz panels so I'll reserve any comments for someone that actually knows what they're talking about.
