Music Producing: Mac Or Pc? Logic Or Cubase?, dilemma between bying a mac or pc Options

[suite156]

hi,

I bougt my first mac (Ibook G4) 2 weeks ago. I really love the OS. Now I am thinking about bying a desktop computer (powermac) for proffesional purpose. I'm a musician and I'd like to make pre-productions on a computer. I have been working with cubase sx on a pc so far, but my pc is no longer powerfull to serve my purposes.
If I would switch to mac, I would have to use logic (as cubase isn't really working well on mac) and buy all the software I already have on my pc. I went to the music shop who has 15 years experience in studio en audio software. He deals bought mac & pc. His answer was clear: if you buy a powermac, you pay double the price than for a pc, which will do the same job perfectly. the only difference is the OS. AND, you pay 3000 Euro, for a machine who has only 512Mb!
I respect his opinion, but I keep looking for different opinions. I want to do a serious invesment and I wonder If I should buy a mac or pc.
I use it for recording audio (not more than 8 tracks) and combinen it with midi

Can anyone help me out?
thx

fanatics & radicals, please spare me your comment. only inteliggent computer users.
fanaticism leads to aggresion.
Respecting each other choices is the better way, that's my opinion.

Why not get both? Today's Macs are based on Intel processors and you can install OSX (Leopard) on a properly built PC. You can install OSX on one HD and XP on another, so you can run Logic, Cubase, or whatever you wish , get familiar with various software applications and decide for yourself which one you'll stick to at the end. There are specialists that can build a serious music computer, pre-install and test the software for you, so you just have to switch it on and you're ready to make music.
