Hi at everyone, i'm a new member of this interesting forum. In these days i would buy a mac pro for audio production. I currently use Cubase on a Windows platform, and now i would switch to Mac platform to continue using Cubase (even with Windows via bootcamp) and in parallel Logic/Pro Tools on Leopard. I apologize for the post that may be repetitive, but still I have not seen a true comparison between these three for audio production.. I'm undecided between the power of a 2.93Quad (but there is the problem of the limit of 8gb) or buy a refurb 3.2Octo Early2008 (even if the price is high: 3600 eur!) or bite the teeth and take a 2.66Octo ( which should be the most powerful among the three). I trust in your experience, thanks in advance!
