My view on vsync is mixed, back when playing x360 2006-07 I do remember seeing tearing but because at the time I didn't know what vsync was an just wanted to play I ignored it and it never really bothered me.
Since moving to PC, learning about vsync etc it now is instantly noticeable everytime it is off or everytime I see it on a mates console and I've never noticed the performance to be affected enough for me to warrant turning it off until Just Cause 2 which for some reason sucked balls at handling vsync. So I'm not sure I'm swaying to turning it off in every other game too, just to get max performance will have to test it out see the benefits/sacrifices.
