I have been given an ultimatum from my wife... buy a new machine by midnight tomorrow night or forever hold my peace... So, I have been reading many threads and trying to get the right advice from everybody, so now I put up my own thread... My choices are: 1) Refurbished Core i7 2) New Core i7 3) Refurbished Core i5 4) New Core i7 The price difference between the new and refurbished Core i7 is 500 bucks... The price difference between the new and refurbished Core i5 is 470 bucks... I almost can't justify the price of a new (2010) model with the refurbs are at such a low price. So, what is the best bang for the money? I was leaning towards the refurbished i5 because at 1530 bucks, it would run circles around my mid-2008 20" C2D iMac and save me 170 off of the Core i7 model. Any suggestions?
