Installing Music Apps On Dual G5 Options

[Milca]

Hello guys
I’ve just purchased Mac G5 dual 2.7.
I also have Mac Laptop where I was running a lot of music apps which I ‘m ready to reinstall together with some new one’s into my new Mac.
I’m gonna be installing
DAW like Pro tools,Abl. Live,DP
And a lot of other stuff like spectrasonics products,BFD ,Kontakt,Absynth and some sample libraries.

Since Dual Mac is for me a brand new thing I ‘m not sure about those two issues.
1) As far as the Mac’s HD – do I need to partition the hard disk and install certain application in certain places or do I just install DAW,plug ins and sample libraries in m”one place”?

2) As far as the dual two processors I’ve red in some posts that you can actually assign power of one processor for example to large orchestral sample library and leave another processor for the rest? Is this really possible?

Hopefully my questions make at least a little sense – if not then I apologize.
I would appreciate any answers.

Thanks for your time
