Hey there everybody, like many of your I have been waiting for the 'up and coming' nahelem mac pro's. UNTIL one of my fellow employee's (at a mac shop) was selling his old G5. he was selling it at a fairly good price with 8 GB RAM, 2.3 dual PPC and an Nvidia quadro 4500. I picked it up for a fairly good price, so I am one happy chap! I just wanted to know are there any restrictions with software because I am using a PPC? I have been intel the whole time, so I haven't had any issues, but I heard some software won't work with a PPC. I use mainly Logic Pro 8 and heaps of third party plugins. Thanks for your help, this machine will be great for the next six months until Nahelems come out I also was wondering which operating system will benefit me more? Tiger or Leopard? Tiger is native to the computer so I was thinking of leaving it, but would leopard take advantage of the RAM? Cheers.
