Did anyone ever try running X-Men Legends II on these specs? I never installed it on my old tower, but I am assuming that if Marvel Ultimate Alliance ran too slowly then the average pre-built XP computer from that era would struggle as well. But maybe an upgraded one would work fine. I do have Windows XP installed on a hard drive for use on my Samsung AMD laptop though with SATA drivers. That is much higher specs than what you are comparing to though. But I bet when I swap that hard drive in to my laptop, it should run anything at all that is compatible with XP.
