How long is pi? The world may never know! But with the advancement of computers, you can now calculate pi to the millionths place. How do you do that? You can use Super Pi, It will let you choose the decimal places as a way to benchmark your computer's processor. The less time, the "faster" the processor. The software is somewhat obsolete with the advent of dual core processors and the latest supported operating system which is Windows XP, but I tried it under Windows 7 and it works! I used CPU-Z to probe for system info and Super Pi for the benchmark.
