So in the bios, my motherboard tells me that if I use a second card (260 for physx or something), usb 3.0 will be disabled. But why is that the case? Do they share the same power or something? And if I don't have any usb 3.0 devices, and use the 3.0 to 2.0 adapter, will I notice any difference with my 2.0 devices?
