Glaanieboy said:PCI-X is used in mainstream servers only, providing a, still parallel, 64-bit bus, running at 133 MHz. PCI-X is backwards compatible with PCI. PCI-E is the new PCI-Express standard, providing a much faster serial interface, running at higher speeds than 133 MHz (I don't know the exact speeds). PCI-E isn't backwards compatible with PCI.
