8pcie leads is good, that is what we use for quad sli for game dev, however I demand Corsair...
XFX would not honor a warranty on a MB that was only a month out of date.
EVGA MSI GigaByte ASrock all have had no issues with me usually sending a newer board if the old one I have is no longer available.
