I'm finally ready to replace my aging G5, and I'm shopping around for a new Mac. I have about $2,000 to spend, so even if new stuff is released tomorrow, I probably couldn't afford it. What is the best machine for working in Photoshop, InDesign, Aperture, and Illustrator all at once that I can get for $2K or under? A friend of mine is offering his Mac Pro 2,1 3gig 8-core for $1,600. It has 6gb of ram, original x1900 video and 250gb hd. I'll probably get two more 1gb sticks. I've also listed a want ad on local craigslist and have found another 1,1 with two dual 3GHz cpus and 4GB RAM. He wants $1,300, so I might as well get the 8-core, since it'll cost the difference to get another 4gb RAM, right? Or, should I just get the iMac i7 for $1,900 after student discount, add 4GB RAM and call it a day? I see it's beating the low end Nehalems, even the 8 core, in everyday computing, but would it beat the older 3GHz models? I have a brand new hard drive and two older 750s that I'd love to pop in a machine, so I prefer the Mac Pro setup over external enclosures. I also like the $4-500 savings, but if that money buys a few more years of use, I don't mind spending it. I loved that my G5 only became 'slow' after I tried to use CS4 and Aperture, giving me 5-6 good years of use.
