I currently hold the records for both AMD and Intel in SuperPI 1M on tech-forums...and when I say "records", I mean for the slowest times.

AMD:


Intel:


The intel one was especially fun, see how the OS was wigging out? That was a machine I just pulled out of the closet at work one day and booted it up. The AMD machine was a customer's machine at the computer shop I also worked at.

Never downclocked to PI though, I may try that with my 720, haha.
