The vid mod extension reports this but it's typically only within
1% of the actual. It's the dotclock value that's fudged by the drivers.
The clocks reported are the clocks requested in the modeline. Due to
PLL limitations most drivers won't nail them exactly.
Whether or not this is useful for you depends on how accurate you
need it to be.
