I was just wondering what the speed is the PCI slot/bus? You can add many different type of cards in them such as a USB 2.0 multi port and ide controler cards, etc. My question is what speed is it capable of inputing and outputing? USB 2 is supposed to be 40 x faster than USB 1. IF your mainboard doesn't have onboard USB and you use an add on card, can the pci keep up? Thanks in advance.
