Watching several reviews, including Linus' it's not really 1ms though since if you put it on that everything looks outright crap.
But yeah, I do play FPS games actually, Hell Let Loose, Planetside, Battlefield, Call of Duty (mostly for campaign/story) and I'll even play CS once in a while but I'm not some kind of master level player, I doubt I have the skill to notice the difference between 1 and 6ms or whatever.
