Question : Intel i processors comparison

Hi
I am trying to decide on a new desktop PC for use in our company and have narrowed it down to one model. That PC comes with the Intel core(TM) i7-860 (2.8GHZ, 8MB) or Intel Core i5-650 (3.2GHZ, 4MB), difference in price is about US$100.
Does anyone have any good comparison guide or info on these processors? The i5 has more GHZ processing but the i7 is a better processor?? Intel's website doesnt have much info apart from how great both are. Any help appreciated on this.
cheers

I dont think diagnostic logging will overload the server.

Here's how to do it.

what will overload the server is - if you start Journaling emails on a regular exchange mail server.

If it's through Outlook - chances of figuring out who did that = ZERO.

If it's done through OWA - you can examine IIS logs
