CPU Stepping (Revision) & CPUID Information
If you're unsure what a stepping is, Intel basically creates a new stepping (or revision) whenever they make a major change to a processor. This usually fixes bugs, adds new features, reduces power consumption, or improves overclocking.

Hi, I have a Dell Optiplex 745 with a RF705 motherboard. I just upgraded to a Q6700 CPU. I was wondering if it is worth upgrading to a Q9650 or a Xeon 3xxx. Is it possible to upgrade with or without an adapter. Any help would be appreciated, and thanks for the interesting article.
