Chances are they still can't get full bandwidth to all 4+ PCIe 2.0 ports because of the chipset. As best as I can remember, X58 acheives Tri-SLI due to an Nvidia Chipset in addition to the X58 NB. To add additional PCIe lanes. But then who the hell knows oui. Overkill or rather not even overkill, it's just plain bragging rights and epeen contests.
