Unusual clock speed on XFX 7900gtx

[Arcane]

Recieved a new XFX 7900gtx yesterday, nice card, however, it appears to have a different clock speed to any advertised! 650, 675 and 700 are the official specs...mines 665 / (800)1600, anyone else had this or am I just "special"?

XFX IIRC are running 6 models of the same cards.

There is the XXX, the XXX-XXX, the Extreme Edition and the Extreme-Extreme Edition etc etc.

Rather confusing if you ask me, so you must have one of the many.
