I am completing a Socket 940 roundup right now which should post in a few days. The Gigabyte K8NNXP-940 is still one of the best. The Asus SK8V is very fast and a favorite of some of the serious overclockers like OPPainter, since it does have CPU multipliers and excellent voltage control. The SK8N is competent, but was the slowest of the boards I am testing, although it did OC fairly well. The MSI K8T Master that was used in the Elite PC gaming system is also quite fast, though overclocking was non-existent.
