Yeah I was fine with 60fps before and generally still am but after getting a 144Hz monitor and playing an older game (Tales of Vesperia) on 144fps, I realised how much smoother it is.
Also now that I have got VR and I stream, I find having the extra performance would be a lot nicer. I play Beat Saber and most of the time it runs at 90fps fine but sometimes I get blips and that messes up my combo and that can also be the difference between failing or passing a stage sometimes!
