So this is what is going through my head. Maybe you can help. I am a music producer / engineer and a film composer. This means I need to run full orchestral sample libraries and record multitrack audio (through Logic, Pro Tools, or DP) at the same time. I have been saving up for a new mac. I currently use a 1.67GHz PowerBook G4 with 2GB RAM and it does not have enough power for what I need. Here are my 3 choices: 1. 24" iMac 2.8GHz 4GB RAM 1TB HDD ($2049 + RAM and HDD upgrade) 2. 20" iMac 2.4GHz 4GB RAM 750GB HDD ($1499 + RAM and HDD upgrade) 3. mac pro 2x2.0GHz or 2x2.66GHz 4GB RAM 250GB HDD + 750GB HDD ($2279 - $2578 + RAM and extra HDD and possibly + $599 for 20" ACD) I know the prices are inconsistent, but these prices are what I need to worry about. Don't ask. (well you can if you really want to. I'll probably answer) Here are the pros and cons of each: 24" iMac Pro: It is gorgeous It has a huge screen I can have the 2.8GHz processor It was my first gut reaction to what computer I should get Con: It may be too big for my desk. If so, I would need to build pillars for my monitors (speaker monitors, not display monitors) and put them behind my desk, which would take up space in the already-small room. 20" iMac Pro: It is gorgeous It would fit better next to my 20" ACD It will fit on my desk Con: It cannot have the 1TB HDD (although I do have lots of external space, I was really looking forward to taking this opportunity of buying a new mac to putting lots of internal space in) It cannot have the 2.8GHz processor Mac Pro Pro: It is highly upgradable (I can keep adding RAM and HDD space) It has 2 processors, so performance is much better It is gorgeous Con: Price is a bit of an issue I really wanted an iSight (but this is not related to my occupation, so it is not a necessity) I was looking at the iMacs because I wanted the screen real estate. I only have a 20" ACD and a 14" Dell display at home, and was really looking forward to more. I could buy a non-apple display but I do not want to. This would add another $600 for another 20" ACD, and like I said, I need it pretty soon, and don't know if I can make the money fast enough. What do you think is my best option? I'm leaning towards the 20" iMac, because I don't know if the .4GHz processor bump and the 250GB HDD space is as important as the space on the top of my desk, and the extra money. Any opinions or help would be greatly greatly appreciated. (and I'm waiting until MacWorld just to see what's new. Who knows what can happen. Maybe a new Mac Pro for a little less money, or the upgrades I wanted from the 24" iMac in the 20" iMac. Who knows? It's better to be safe than sorry) Thanks!!!!!
