On my G4/500 single processor with 640 meg of ram (you don't need this much ram), 2 x 7200 rpm IDE HDD and using the Digi001. I should get 16 tracks recording simutanieously, but I have only recorded using 12 tracks (haven't tried 16 tracks yet).
You will get in real time plugins..... 24 tracks with 1 x EQ, 1 x comp , 24 x bus sends on each track. On buses you should get 1 x reverb (this is the cpu killer), 1 x slap delay. On master fader you should get EQ, limiter, comp.
If you want more plugin count, get the Mac G4/733. Oh and don't forget you have Audio Suite plugins for effects if you lose cpu power.
