LOL, I upgraded to 2002 earlier today and I didn't even realize that it was released today. I think this is funny because I have never updated it, and today was the first time. I guess I'm claravoiant or however you spell that.
I don't really see too many big differences...except that they let you select the system that you bench against...they had it in the free version but never in the pro version and I hated that. Well, I'm happy.
Power/aux temp is usually your PSU temperature...although it can be something else too...depending on how you set it up.
