No. Their chipsets give a 16 PCIe 2 lanes and 4 PICe 1.1 lanes, so you have a 16x2 PCIe slot for the gfx card and a 4x1.1 PCIe slot (or 4 1x1.1 PCIe slots). USB 3 is faster 1x1.1 PICe, so you need a 4xPICe USB3 card. Most USB3 cards are 1xPICe, though. If you need USB 3, get an AMD board. All PCIe lanes are 2.0 Best Martin
