Hi folks, I have been looking to upgrade my 3,1 Octo 2.8 soon and have the chance to buy this for £400: Apple Mac Pro "Eight Core" 2.66 (2009/Nehalem) 6GB Ram 640GB HDD Its all stock as far as I know, so 6Gb of ram and a 640GB hard drive. I'd be upgrading these heavily. What do you think, decent deal for £400? Also, am I right in thinking that this model can be firmware upgraded into a 5,1 and then I could add a pair of processors like this: http://www.ebay.co.uk/itm/Intel-Xeo...246?pt=LH_DefaultDomain_0&hash=item35e77e8166 And also use 1333Mhz ram on it? Would this make the machine exactly the same as a 2012 5,1 Mac Pro? Thanks for any advice and help you can offer!
