I would like to know if it is possible to upgrade the processors in my early 2008 mac pro. I have a 2 x quad core 2.8 Ghz early 2008 mac pro which I use for heavy lifting image processing. It runs a Apple RAID card with 4 WD 3TB Hard drives and an OWC PCI 480GB SSD for boot and apps. Its kitted out with 32 gig of ram. I really want to keep extending this machines life rather than purchasing the new model and a processor upgrade seems the only way left to move forward. From what I have read a processor upgrade to 3.2GHZ is theoreticlaly possible. This was the fastest processor apple offered in this model. Im just not exactly sure what parts I need to make this work. I found these processors on ebay which I 'think' are the right ones? Processors Any help would be greatly appreciated.
