"Unlike some other manufacturers, MSI has chosen to use the built in PLX chip, specifically for Marvel and NEC, to provide for SATA and USB 3.0 performance. The PLX PCI-e bridge chip is specifically designed to increase (multiply) bandwidth and effectively distribute that bandwidth across the PCI-e lanes when using the 3.0 functions. Other manufacturers have chosen to forgo the PLX, which forces USB and SATA 3.0 to occupy the graphics PCI-e lanes causing a bottleneck and decreasing graphics performance."
