I really love towers. Unfortunately, even a used Mac Pro is well outside my price range. Lately I've been looking at the quad core Powermacs as a potential desktop system. I'll say this, I do have Intel based Macs that are probably faster, but I'm using a dual 2.0GHz G5 with 2GB of RAM as my primary desktop right now. Its great, and I really don't think it feels any slower than my 2.16GHz MacBook Pro with 3GB of RAM. I really want a quad core system for doing video compression, and most of the applications I use are still PPC (Adobe CS2 and Final Cut Express) so they're going to work great on a G5. Is this really that bad of an idea to buy one? I mean, Apple's support for 10.4 is still pretty good, so I don't think they'll kill off Leopard support for at least another 2 years since so many Intel Macs shipped with it and all remaining PPC users are stuck there. So what do you think? Is the quad G5 worth buying in September 2010?
