I'm looking to buy my first Mac and I'm on a very limited budget. I've been looking around on ebay at G4 Powermacs and have found a few good deals, especially on dual MDD's. Do you think one would be a good purchase to make? My current setup is running at 2.0Ghz with 512mb ram. For rendering with Blender I also use an old Compaq with a 867mhz processor and 128mb of ram. I was thinking about getting a good priced dual 1.0 or 1.25 and upgrade it to 1.5 GB b of ram if needed. I will be using Blender and gimp mostly. Would this be good for my needs or should I just save my pennys for another year or so and get something then?
