Business Winstone
I still like this benchmark for judging office application performance.
Here we see the E6600 beating its nearest competitor the X2 5000+ by 2%, and the overclocked result dominates the stock results as well as the overclocked result for the X2 5000+
You would not be dissapointed if you used an E6600 at stock speeds for the office.

Multimedia Winstone
Once again, we see the E6600 slighly edge out the X2 5000+, and the overclocked E6600 dominates the overclocked X2 5000+ and all the stock results.
The Core 2 Duo E6600 rocks for multimedia apps.
