Which Mac? Which Os?, Mac hardware search Options

[Angelgob]

Hello,

I have to upgrade now from my good old beige G3, b/c I am running out of processing power!

I probably won't dare to take the plunge with a G5 just yet, so which G4 would be the best (second hand or new) to buy? And which OS should I use and which audio card? At the moment I am using the audio in/out from my Mac.

I have Cubase 5, Recycle, reason and rebirth. I will need a sccsi card for my sccsi audio drive and to connect with my sampler to send stuff from recycle over. Should I get a serial card/connection with the G4 to connect my serial midi interface or get a usb one? (I heard the usb midi interfaces weren't as good as the serial ones?)

I am going to the Mac Expo in London this week, and would like to be able to ask some intelligent questions.... :-)

Thank you for taking your time and giving some advice if you can.
