Well cool, I have a pretty damn nice pc at only 2.4ghz with a gig of ram. But it is old by todays standards, but it does just fine in cubase sx2 with loads of softsynths and plugins. I recently was considering buying a tc electronics powercore and thought to myself; "What is the point?" I have plenty of power with my computer, before I didn't think I had enough power but it turned out I didn't know how to use my machine properly. That ddr2 ram seems cool and so does the pci express on the new pc's.
The mac's are cool and stuff, but honestly I don't see how they are better than a pc in any way shape or form. Pc's and Mac's have the same technical probelms, pc's it is drivers, mac's it is extensions. I have read about Mac users having to reinstall the whole system just like us pc doods do. I am just as good with a mac as windows, yet you can buy a crazy nice pc or build one for ~$1,000 or you can buy a used mac on ebay for ~$2000-3000. I would never currently be able to justify the cost of a mac. For one, I don't see how it is any better, Next it costs 2x as much, then with current updates in the pc world I don't see the point. I know people say oh IBM developed the new processor for the G5 and it is just so amazing. I have used G4's a bunch and they seem like every other mac I have ever used, which is just like a pc. I know everyone says macs are better for art, well that is better general of a statement. The only "edge" mac's have over pc is in video production, that is their niche market. I suppose you can include audio into the mix, but any computer can do audio, lol. You don't need a new dual processor G5 to make music, at least music that people want to listen too. Perhaps if you do film scores that have a full orchestra of samples, even then I don't think you need a G5 for.
Of course if I had tons of money I would buy a super fast computer, and I guess that would be a G5, since it is the most powerful computer on the market, or is that just a marketing gimic. Sorry to be skeptical, but advertising doesn't real break through to me, so apple paid a bunch of people to rate the G5 high, at least that is what GM did with the M300 car of the year. I don't even have proof that they did, I don't need proof. You can buy any product that is highly marketed and it always blows compared to the unit that is superior in every way shape and form that is not advertisted. I don't even think apple gives a rats ass about music, they care about the money though. That is why the pc market has opened up to music production, enough small users do it now that it is a marketable product.
No one really actually cares about music production, only we the artists do.
