The below statement is taken from Wikipedia, how true is the comment that there is no performance benefit in regards to graphics performance?

AMD latest flagship graphic card, the Radeon 7970, launched on January 9, 2012, is the world's first PCIe 3.0 graphic card.[23] Initial reviews suggest that the new interface would not improve graphic performance compared to earlier PCIe 2.0, which, at the time of writing, is still under-utilized. However, the new interface would prove advantageous when used for general purpose computing with technologies like OpenCL and C++ AMP.

It is generally very true, pcie 2 x16 is generally more than enough bandwidth. If you start using triple SLI+ configurations at multi monitor resolutions then you will start to see a benefit.
