Logic pro 9 on 2ghz dual mac pro

hi guys quick question,

im looking to get into music production and have purchased logic 9 pro. i am a apple newb and was just wondering whether a 2ghz mac pro will be powerful enough to run this software and not lag. i have seen 2.66ghz for sale aswell and wonder if it makes any difference?

cheers

Is it the Core Duo or the Core 2? I've recorded up to 7 inputs at a time on a C2D MBP and worked with projects with upwards of 50 tracks.

The biggest problem I encountered was due to the software. Logic pe Logic studio wasn't the most stable software ever. When I upgraded to Logic Studio, things started going more smoothly for me. I think that was Logic 8, iirc.

if it doesnt work out for you, you can sell it to me

how will i know the difference? its a intel xeon 2ghz A1186 if that helps???

guy that works at guitar center has an old macbook w/ 2GB of RAM and hes running Logic 7 express and he says it does it well. I know the full Logic 9 has a lot more in it than Logic Express but I wouldnt know what the difference is...

Ive heard people talk about how their 4GB are almost at their limit but I have no idea how they know or how I would be able to tell if my RAM needs to be upgraded ??
