In my A+ hardware course there was an arguement about the new PCI-E for video cards. I was hoping someone here could shed some light on the subject mainly concerning the PCI-E slot. Is it like PCI slots and use the motherboard bus with busmastery or is it like AGP and have its own bus? And how fast do they actually operate. I found some information on how fast the PCI-E can and should run at but nothing on how it actualy runs. hope someone can shed some light on the subject.
