Some people just like very high framerates - when I was more seriously gaming I always used to buy either high end or one back from high end SLI setups even though I played 1-2 steps down resolution wise.
These days for single player I'm pretty happy around 60-70 FPS with G-Sync though and for multiplayer generally turn a lot of settings down anyway for a clear image.
