your refresh rate is what your monitor or tv puts out. likely if you don't know it's 60hz which means your fps is limited (sorta) to 60. you should turn vsync on if your getting screen anomalies from too high, too low, or fluctuating frames. what card are you running, and what monitor/tv?

couldn't find any decent info on your monitor's refresh rate which again leads me to believe it's 60hz, with a 7850 you should be good for around 50fps on most games (not battlefield, crysis, etc) with that said you would want to set vsync on so that in the case of it going above that 60 mark it won't cause screen tearing. this is mainly an issue with your gpu's power, but the cpu can hurt it if it's under powered for the system.
