Same as the standard 1007 but with a few extra features that Asus disabled.
Some people experience less overclocking ability with anything later than
1004, but I think that is generally related to Rev 1.0x boards, essentially
FSB is down a bit, but overall max MHz is 50-100 up.
I've been using the standard 1007 for a few days and it's been fine. I'm
not overclocked at the moment though, but I suspect that it's similar to
1006, FSB could go to 220MHz. I have a Rev2.0
