I can understand some of the manufacturers not being too quick to add these to their mobo range, but this step from Gigabyte is good in 2 ways for me.
1stly it signifies their commintment to the amd platform is strong, whilst including my 2nd favor - which is, new tech for the Intel ranges is being quickly supplied on the amd side of things which gives me the +ve feeling about the mobos.
Maybe hard to explain, but I felt during the am2 transition, some of the mobo tech that the Intel mobos were enjoying didn't seem to carry through to the amd mobos.
