First up, there's an announcement here, on Beyond3D.com, its a couple of weeks old but has some valuable information.
Also, there's an article here from The Inquirer, which gives details of the alliance between ATI and Intel to perfect and push the new PCI Express standard. As you will read, Intel and ATI are "partners" in this venture.
[COLOR=royalblue]"According to both companies, the first generation of PCI Express will be driven by photo realism, the "digital home", god preserve us, next generation graphical user interfaces, and, above all the peak bandwidth of 4GB/s bidirectionally for the X16 link."[/COLOR]
Mind you, I am sure we have all heard all of that "photo realism" stuff before. Could this be the technology to finally deliver? Could be. Post here if you wanna discuss it.
