The only thing with the GA-P55M-UD2 LGA is that it is a micro. other than that it is basically the same as the other Gigabyte (one less SATA port, has Firewire onbord, everything else about the same) except for missing a PCI-E x1 slot and two PCI slots.
mATX boards sued to be bad about heat retention as everything was closer together. If you have good air flow that shouldn't be a problem.
Yep, agree, look at the description of the rep I gave you, it wasn't meant in offense it was kind of a joke I didn't think over.
