Ok I'm buying a refurbished Mac Pro 6,1 today. 6 core (upgrading to 8) 512 flash. Question is.. should I get the d500 or d700 ? there is a 184.88 dollar difference between the two after taxes. This is to hold me over until the new Mac Pro's are released and would like to add value were I can to separate this from all the CPU swapped D300's you see on ebay. I'm also getting apple care to help with resale value and some protection. I'm guessing it would be worth around 2k (1k hit) when it comes time to off it. either way , would the d700 be advantageous for a mere 184.88 dollars?
