LAST EDITED ON Feb-15-02 AT 06:30 AM (GMT)I have obviously been way out in the wilderness here, but could someone explain the differences on cnr, amr, and acr. I know that they are communications bus for the mobo, or something like that. Last I had heard PCI and ISA connections were the standard for modems, and network cards. Could someone also give me a brief rundown on the difference between and athalon and duron chipset (if I was lookin at the same speed cpu)
