No it's not, PCI-X is based on PCI, but PCI-Express is not:

PCI-X is a 64 bit extention of PCI, PCIe is a serial bus. It's like PATA vs SATA.

PCI Express architecture is a state-of-the-art serial interconnect technology that keeps pace with recent advances in processor and memory subsystems. From its initial release at 0.8V, 2.5GHz, the PCI Express technology roadmap will continue to evolve, while maintaining backward compatibility, well into the next decade with enhancements to its protocol, signaling, electromechanical and other specifications. The PCI Express architecture retains the PCI usage model and software interfaces for investment protection and smooth development migration. The technology is aimed at multiple market segments in the computing and communication industries, and supports chip-to-chip, board-to-board and adapter solutions at an equivalent or lower cost structure than existing PCI designs. PCI Express currently runs at 2.5Gbps, or 250MBps per lane in each direction, providing a total bandwidth of 16GBps in a 32-lane configuration. Future frequency increases will scale up total bandwidth to the limits of copper and significantly beyond that via other media without impacting any layers above the Physical Layer in the protocol stack. PCI Express provides I/O attach points for high-performance graphics, 1394b, USB 2.0, InfiniBand™ Architecture, Gigabit networking and so on.

Stanger is right. They are not the same at all.

I was pretty sure I was right, but I though maybe I missed a memo or something. Plus I just came back from a week's vacation in OBX, so am not in full gear yet.

The confusing part is that from a software standpoint PCIe is the same as PCI.

There is a virtual drive programme for x64.

Its called "file disk".

PCI-X is what Apple adopted for their Mac G5s to replace the old PCI. But they still use AGP for the video card.

PCI-E (Express) is what PCs adopted as the next generation replacement for the old PCI and AGP. PCI-E has two versions, 16x and 1x. The 16x is used to replace the old AGP. And the 1x is used to replace the old PCI.

Its stupid that they labeled them PCI-X and PCI-Express, like they purposely want to confuse people or something. But, with Apple switching to intel processors, they might as well drop PCI-X and adopt PCI-E also so that they can make use of the next generation video cards that are produced for the PCI-E market.
