For me its fine either way because I still play oldschool games from NES/SNES era and even N64 that have worse Frame rates but playing a game at 60 FPS is much more enjoyable for me.

 

And yes, its very noticeable - for an example playing GTAIV on PC and on PS3 really shows how different 30 FPS and 60 FPS is like.
