Hi everyone. I am currently looking into switching from PC to Mac, as I am always being told how great Macs are, especially for music production, as that is what I am looking to buy it for. My budget is not exactly big at this point, so a brand new Mac is out of the question, for now anyways. I'm thinking about just getting my feet wet and there are two on Ebay that I am contemplating. Problem is, I am not well-versed in Macs as far as what will work for what, so I am here hoping someone with lots of Mac experience can assist in putting me on the right path. Specs for both are as follows : iMac # 1 G5 17" screen, 1.8 Ghz processor, 768 RAM, 160 G hd, with superdrive iMac #2 G4, 15" screen, 700Mhz processor, 512 RAM, 80 G HDD, also with the superdive. I realize that the question may be dumb, especially since the G5 is obviously more powerful than the G4 ( if I don't win the G5 then I am stuck with the G4 anyways ) but I am curious, if I am only running Logic on the computer, and a few plugins, am I going to suffer greatly with the G4 ? The G4 also comes with iLife preinstalled, which means GB will be on it. So, if I cant use Logic on the G4, will I be able to get decent performance out of GB if that's pretty much the only thing I am running on it ? I apologize for the long winded post and for the nOOb questions, but I am stumped. Ive been recording on PC for a number of years, and windows just kinda blows for recording anyways, I know Ill be happier with the Mac. Just looking for helpful opinions. Also, the OS on either iMac is pre-installed and no back up discs are going to be available, doesn't that violate some liscensing laws with Apple ? ( If I got the G5 I'd just buy Leopard and throw it on anyways. ) Thanks in advance everyone, I'm sure Ill be better off than I am now regardless of how it rolls but, hopefully some sage advice will help steer me right.
