nVidia first said that twin PCI Express x8 slots would be enough to keep the SLI dual graphics masses happy but how wrong they were. Users are starting to use higher levels of AA and AF settings and resolutions keep getting higher (even hitting the 2046 x mark now) and to keep that type of resolution and graphics quality level happy, you need some monster hardware and a powerful interface for them to communicate across - and dual PCI Express x16 is the only way it can be done if you are really serious about your gaming.
