It would be more complicated soon as more and more people start using the new Athlon 4/MP / Duron mobile 'cause they support 3DNow! Professional (full Intel SSE). The configure script (the user?) have to decide which one to use (3DNow!/3DNow! enhanced or SSE). Gareth which perform better on Athlon / Duron? If I remember right you found that 3DNow! on your Duron 600 was faster then SSE on your PIII 700 mobile?
