obviously more data to transfer by the two HDMI ports,i think this is the saint grial that all of us we are looking for long time,the definitive solution to the PCIE full 16X speed as a desktop motherboard,there is one problem still to solve wich is the internal display,we will have problems with this but i think with the last version of the EXP GDC M2 M key with two hdmi links will be not more problems for our external gpu's with a external display,i dont think we will lost more than 2% of performance with this one or maybe the speed is so high that we will dont lost performance at all.i already have purchased one for me,I'LL TAKE IT¡¡
