Came across this small and nifty tool which provides an insight into how speed your processor is with a multitude of tests. Its an installable of a low size and takes a moment to spring to life.
Here is how it provides info, with other options and you can even compare with the around-the-world reports to know where you stand in the CPU Speed Race. 
Pretty Cool interface, right? Try it here: CPU Speed Professional
I downloaded this tool and find out my Mhz is 1529, not sure if thats good or bad for an 8 year old computer.
