Regular PCI and PCI-X (eXtended) is: 33hmz/32bits 132 Megabyte 66mhz/32bits 264 Megabyte 66mhz/64bits 520 Megabyte 100mhz/64bits 784 Megabyte 133mhz/64bits 1040 Megabyte etc. With overhead included I'd say 100 Megabyte is pretty reasonable for a normal pci bus. Keep in mind that this is for the whole bus, which is why most server motherboard have multiple seperate busses. PCI-X is an extension to regular pci, with more mhz/bits. PCI-E ( Express ) is a redesign with higher speeds and fewer traces needed. The big problem with 64bits pci is not the slot but the fact that you have to run all those extra (fast) lines to the slots which means that you'll need extra space (mainly layers) to store them, ergo an expensive motherboard.
