The CPU is Overclocked to 6Ghz.
My Quad Core is 2.4GHZ, i have only overclocked it to 2.75.
He had a 3.2GHZ chip, and he got it to OVER 6ghz.
3.2GHZ is about the best you can buy btw, so almost doubling the speed is unbelievable.
Another way of looking at it is:
He spent about 2 grand on his 3.2, he is getting 6 out of it. so he is making a 2 grand product a 5 grand one.
