With the release of the 890FX chipset, ASUS steps up to the plate with their latest top of the line AMD motherboard, the Crosshair IV Formula. Most of the new features for the 8-Series chipset can be found in the SB850 southbridge, the most notable being native support for SATA 6Gb/s. Like the 790FX chipset, the 890FX has 44 PCIe 2.0 lanes, allowing for CrossfireX dual x16 graphics card support.
