Long story short, I'm still using a PowerMac G5 Dual 2.3 as my main computer. I also have an Early 2008 MBP 17" 2.6Ghz, 4GB Ram, 512Mb 8600GT and Hi res display which is used when I'm video editing and editing photos (intel architecture is needed for software). I'm looking to upgrade my desktop to a Mac Pro, I was looking at 2006/2008 models but I was wondering what the average price for a 2009 Quad core is? I'm currently looking at one with these specs, Quad Xeon 2.93 8GB of RAM 2X600GB HD 2X1TB HD Nvidia Quadro 4000 It obviously has a few upgrades but what is it likely to go for? It looks in ok condition with some serious scratching to the rear top handle.
