Last thing - Does anyone know how much Linux is actually able to make use of the Altivec instructions on the G4? PowerLogix has a G3/1.0Ghz that I am thinking about getting, and if there isn't that much support for the Atlivec, is there any other reason to stay with the G4? Thanx
Unless the apps are compiled with -mcpu=G4, no altivec will be used. I tried that recently on a G5, the overall amount of generated altivec code was low. Either because there was nothing to optimize, or because gcc isnt smart enough.
