nVidia's nForce4 SLI X16 remains the top of the line chipset for Socket-939 processor owners, as its excellent base feature set and dual PCI Express x16 graphics cards slots have fended off all potential competitors. The largest threat has been ATI's Radeon Xpress 3200 chipset, whose feature set was largely similar to nVidia's, but also boasted far lower power consumption levels. While this chipset was an excellent performer, ATI's Southbridge technology remained somewhat lackluster compared to nVidia's, and ATI's backup plan, relying on ULi Southbridge controllers, fell through when nVidia purchased ULi and largely put a halt to that.
