There is a nice little application out there called Y-Cruncher.
You can use it to benchmark your CPU by calculating pi up to various lenths.

If anybody wants to post their results for various levels, such as 50M, 100M, 500M, or a Billion digits.. it would be nice. :D
( my bets are on Aaron Lee for best time )
Here are my results for one billion digits.
