Wow, a 60 Hz mode would definitely make me think of considering the Crystal. The resolution is insane, a low fps mode is a must for me.
I now actually use Reverb G2 in 60 Hz mode (one of the few headsets (or the only one?) that supports it) because I prefer maximum detail and fluidity (no reprojection) over framerate.
I don't know how much time I will be able to use it (you hear me Microsoft!?), and there is not much to choose from (I'm thinking BSB and Pimax, because I prefer direct connection to GPU)
