I used to have a amithlon install on my p2 266 with 196mb ram. I used a geforce2 video card and the system was amazingly fast on workbench and rtg. It was ideal for irc, or a bit of web browsing. Of course, trying to run e-uae for classic games was a no-no, because of limited cpu already being used in an emulation instance. I noticed that giving the lack of cpu available regarding the minimum told by the creator of the soft, it eated a lot of the ram, i suppose in order to equal the system about cpu speed. In the end, the system had 64mb of fully usable ram after amithlon booted, and that´s a lot for an Amiga.
