Hello! I'm a professional Video Editor (I say this so you know RAM and Processor are important to me) and I'm needing to do an upgrade. I have an old Mac Pro that was a powerhouse machine in its day. I'd like to find out: A. How much is it worth if I were to sell it? B. Could I upgrade this to a Quad-Core+ machine (Mac or Hackintosh) that will last me a year or two so that I can save up for a brand new machine? Would that even be worth it? Model Name: Mac Pro Model Identifier: MacPro1.1 Processor Name: Dual-Core Intel Xeon Processor Speed: 3GHz Number Of Processors: 2 Total Number Of Cores: 4 L2 Cache (per processor): 4 MB Memory: 12 GB Bus Speed: 1.33 GHz Boot ROM Version: MP11.005C.BO8 SMC Version (system): 1.7f10 Comes with a giant Apple Display for video editing.
