Dear All, To cut a long story short - after reading through the great expert opinions on these forums, I've seen the light and am changing my 2.66 Ghz 12-core order to 3.33 Hex-a-core... My MAIN reason for this is that it will be the fastest for anything I want to do in the next year or two. Beyond that hopefully a fully revamped SandyBridge Mac Pro should be out. I would then hope to be able to sell my 3.33 Hexcore and buy the new model, as i have read several others intend to do. My question is: How confident can I be of being able to sell the hexcore model in 1-2 years time? Has anyone had success selling 'last years' model to buy the latest one? Do you sell them on eBay typically and what kind of a loss can I expect? Thank you!
