Originally planned for the end of 2009, the new PCI Express format will only be officially released in June 2010. So it will only be at the beginning of 2011 that the first computers based on such format will be available. Technically, this is not a real issue, as the current PCI Express 2.0 format is not a limiting factor for current graphic cards. It might become the bottleneck of the system when massive usage of GPGPU will push needs for larger and bi-directional bandwidth. Indeed, data sent to the GPU will not be displayed, but will have to be exchanged both way with the CPU.
