I'm looking for a DSP solution, I'm looking for a way to relieve my CPU Options

[karambos]

I run Logic natively (i.e. the C.P.U. takes care of everything) on a Rev ‘A’ (i.e. no slave drive allowed) 233Mhz Mac G3 and when I’m playing back about 8 to 10 tracks with various effects, my system maxes out. I recognise that I could go out and buy a G4 but I was wondering if would not be a better idea to buy some sort of non-native (i.e. DSP card) solution. I’ve looked into the following cards: TC Powercore, Digi Design 001, Yamaha DSP 2416, Creamware Pulsar and Scope. But I’m still a little confused about what I’ll be getting myself into. I want to be able to run all the audio and all the effects on the card. Is it possible to run my present VST plugs on such a card (I’ve recently invested in the “Pluggo” plugins from cycling74) or will I be limited to the effects written by the manufacturers specifically for the card? Are there DSP cards that just do the audio and others that do both the audio and the effects? I’m using an Audiowerk 2 soundcard at the mo – would I have to change that too? Or do such non-native solutions come with the necessary audio card as well? If I bought a DigiDesign solution like the mix plus (this is just an example I can’t actually afford this) can I run effects from other DSP card manufacturers like those of the Powercore card? Would I want to?

Or should I start saving for the G4?
