Find out GPU operating frequency ?

I’d like to know if it is possible to find out the GPU operating frequency of the specific GPU that I am using ?
I am using Quadro FX5600, GeForce 8800GTX.
I want to know for Quadro especially since it is 675MHz for Geforce.
Thanks

You can get this information by running the deviceQuery sample from the CUDA SDK.

or by downloading gpu-z, google for it its free. it also tells you useful stuff like shader speed, core speed, bandwidth etc etc.

Thanks a lot
