Richard needs a PCI-e card and wants to know who has the best one because the prices are so vast. He's also wondering what "superspeed USB 3.0" is.
Leo says a PCI-e slot is faster and if he has that on his motherboard, that's the type to choose. As far as brand goes, Leo says they're pretty much all the same and are probably using the same components. A USB 3 card won't do him much good unless his devices are USB 3 supported. Luke in the chatroom bought a cheap card from eBay and says it works fine. He should just be sure he has the drivers for it.
