Both have crossfire/sli which matters to me.. I would rather go with the cheaper one, but was wondering the difference between a micro and non micro MOBO
The difference is in the size of the board, which means less or more expension slots. If you look at the two boards you have list, the difference is two PCI-e 1 slots, one PCI slot and one SATA port. The micro board just isn't big enough for all of the additional slots.
