    This is a quote not me:

    "PCIe is a technology under constant development and improvement. In 2004, Intel introduced PCIe 1.0, with a data rate of 250 MB/s and a transfer rate of 2.5 GT/s. Later, version 1.1 offered minor revisions to the specification. On 15 January 2007, the PCI-SIG announced the availability of the PCI Express Base 2.0 specification. This doubled the data rate of each lane from 250 to 500, and the transfer rate from 2.5 GT/s to 5 GT/s. PCIe 2.0 is backward compatible with PCIe 1.1 as a physical interface slot and from within software, so older cards will still be able to work in machines fitted with PCIe 2.0. The proposed PCIe 3.0 is scheduled for release around 2010."
