IMHO it's a typo, 3DM05 not '06. That sounds more realistic. Anyway you look on it, AgenaFX@3GHz scoring 30k 3DM'05s is a really superb result for graphics cards clocked so low.
P.S.: It means that overclocking software for crossfired ATi Radeon HD2900XT graphics cards exist, it just isn't public yet :D
