Hi guys, I enjoy making music but I'm not a trained audio engineer (a hobiest) I've been using Logic 8 , Reason 4, and T-racks,all in the box production. These are installed on power mac desk top 1.1 which I bought just as Intel took over the brain space "well nobody told me" so as you can imagine it wasn't long before it hit the upgrade ceiling, but that was cool, as I was working out the techniques, short cuts and work flow stuff, anyway it's got to the point where I'm looking to upgrade and I'm looking some advice on which model to consider 3.1, 4.1, the different operating sys, and what to prepare for. Those are the main 3 programmes I use for composing editing and junior mastering, but don't wont to buy a machine to then be told " this carnt work or that carnt work upgrade the operating system" or somthing like that!! I just want to get a bit of distance with the next Mac Pro I get !! I'm doing the eBay/amazon thing (got kids to feed) 500£ or 650£ (If I don't) lol yep I'm in the u.k but your advice would be much appreciated.
