 Although the CrossFire Xpress 3200 chipset is indeed capable of CrossFire through the PCI Express bus for every Radeon series below the X1900s, the driver accommodations for this CrossFire method have not yet materialized for the X1800 series.ATI has said that future revisions of the Catalyst driver suite will contain what is required for X1800 dongleless CrossFire, but has not yet mentioned a specific date.With the release of the Radeon X1950 Pro (RV570 GPU), ATI has completely revised CrossFire's connection infrastructure to further eliminate the need for past Y-dongle/Master card and slave card configurations for CrossFire to operate.
