I had a Pentium D 3ghz CPU installed in my PC (Windows Vista 32bit). On this chip I got a windows rating of 4.8 for calculations per second. I decided to upgrade to a faster CPU, so I installed an Intel Core 2 Duo chip, 3.06Ghz. The windows rating has fallen to 4.7. Any ideas why I am getting a slower speed from a faster chip? Any clues on how to correct this? I'm sure this new chip should be a lot faster.
Hope you can help folks
