My impression is the PPC only really helps with OS4, and with PPC specific software.
PPC helps with mp3 playing,video,rtg gfx(if cvppc is added),pdf viewing,fx scan,mp3 encoding,vhi studio,archiving,fxpaint,some ppc only games,imagefx ppc operators,candy factory,lightwave ppc hooks,etc under os3.x and more i haven't even touched on....CSPPC also gives you very fast UWscsi at 25MB/s+ with up to 14 devices. And the Csppc addresses ram from the ppc side in 64bit.The blizzardppc only in 32bit w/narrow 10MB/s scsi w/6 devices.worst case the csppc is a 060 accelerator with 128MB ram.
Sorry to hijack the thread,but had to reply to this common misconception.It really makes an amiga quite useable.
