Actual a PIII at 2 Ghz doesn't exist, not even the best overclockers get the P3 over 1.1Ghz when running chessprogs on it. So obviously i go for the extra speed. I get more as 1.7 with diep though, so it's not even 1.7Ghz when compared to single cpu. It's way way more. > The only problem is that not all the programs support 2 processors. > But there is another side of the medal.
