I've found that my Athlon XP 2200 is noticably faster at Gnome than my Athlon MP 1500 (running a UP kernel). The memory and disk is the same speed, so only the processor is different, unless the chipsets make a huge difference. Of course, both are much faster than my 1 GHz Athlon laptop, but there's also a large disk/memory speed difference there. -- Daniel Gryniewicz
