When I mentioned QC, I was referring to them checking things on the line, MSI has a high number of DOA mobos, and failures within 30-60 days and of no particular rhyme or reason, their Z87 G45 has seen numerous problems with the Sata ports, USB ports, sound and of course the relaeas with the problematic Killer NIC ethernet ports, but it's about the same with all their mobo lines, ought to cut back on their hype advertising and invest the money into a few folks on the production lines
