Is a pci express 2.0 card compatable with a pci express x16 slot?

we had a discussion on this a couple of weeks ago here is an extract from wikiki
PCI Express 2.0

PCI-SIG announced the availability of the PCI Express Base 2.0 specification on 15 January 2007.[4] PCIe 2.0 doubles the bus standard's bandwidth from 2.5 Gbit/s to 5 Gbit/s, meaning a x32 connector can transfer data at up to 16 GB/s in each direction.

PCIe 2.0 is not completely backward compatible with PCIe v1.x. Graphic cards and motherboards designed for v2.0 will be able to work with v1.1 and vice versa, however v2.0 cards will not work in v1.0 and v1.0a motherboards.

The PCI-SIG also said PCIe 2.0 also features improvements to the point-to-point data transfer protocol and its software architecture.[5]

In June 2007 Intel released the specification of the P35 chipset which does not support PCIe 2.0 only PCIe 1.1.[6] Some people may be confused by the P35 block diagram[7] which states the Intel P35 has a PCIe x16 graphics link (8 GB/s) and 6 PCIe x1 links (500 MB/s each), for simple verification one can view the P965 block diagram which shows the same number of lanes and bandwidth but was released before PCIe 2.0 was finalized. Intel's first PCIe 2.0 capable chipset is the X38 and boards are already shipping from various vendors (Abit, Asus, Gigabyte) as of October 21, 2007.[8] AMD starts supporting PCIe 2.0 from its RD700 chipset series. NVIDIA has revealed that the MCP72 will be their first PCIe 2.0 equipped chipset.[9]

[edit]
PCI Express 3.0

In August 2007 PCI-SIG announced that PCI Express 3.0 will carry a bit rate of 8 gigatransfers per second. The spec will be backwards-compatible with existing PCIe
