Vsync - on or off?

[MoRT489]

So I see lots of people say turn it off to increase frame rates, but this can cause tearing. if my monitor is limited to 75Hz with vsync on, when i turn it off and get say 200fps is it actually making 200 frames per second, if so why is the monitor limited to 75 and why ever have vsync on?! I may just not understand the situation, any clarification welcomed

are there any LCDs/TFTs that refresh at more than 75Hz?

ack! Maybe the reason tearing looks so bad on a LCD is because the 'refresh rate' is 60 or 75Hz.. I couldn't play Quake2 in 75fps.. 85fps was needed and 100fps+ is even better.

I've played some games reasonably smoothly at 35fps and most people on here report playing crysis at between 25 and 35 so how is 75 fps not enough for quake?!
