...to upgrade to a Core 2 Duo iMac? I have a 17" iMac G5 running at 2.0 GHz with .5 GB RAM, a 160 GB internal hard disk, and a Superdrive. I bought it on 5/5/05. I've been using Final Cut Express HD with it, and it's been a great computer. I'm also very proud that I paid for most of it (which was a lot for the time.) However, I'd like to upgrade to Final Cut Studio, and also speed up my mac, as well as get some more hard disk space (I have 180 GB in external hard disks.) I was planning on upgrading to another 1GB of RAM, which is close to $100 there. And I'll probably have to buy another external hard disk soon, too, which will be about $200, so that's $300 in upgrades right there. I've looked on eBay, and if I were to sell my iMac G5 with iLife '06, Office, and Final Cut Express, I could probably get close to $1,000 for it. The iMac Core 2 Duo I'd get would be somewhere betwenn $1150-$1399 (I can get an edu discount.) My question is: would it be worth it to upgrade? Would I notice that big of a difference when working with Final Cut and the other apps I work with? Should I just save up for a more powerful machine (like a Mac Pro) later on? Thanks.
