Efficiently that is? Granted, I don't have a AGP X8 Video card (if Doom III requires one, which I doubt), but my current system, is more powerful for the 'age old' Quake III engine based games (Alice, FAKK2, RTCW, SOFII). Not to mention that none of them utilizes the features that are found on nVIDIA based video cards, all the way back to DD256 version. The only game that I think stresses my system is Unreal Tournament 2003. Bottom line: Can my current system run Doom III efficiently?
