I just got in an argument with the sales guy at Compusmart because I wanted to see the difference between the 12 ms and the 16ms monitors. He told me that I would not be able to see any difference that they're so close that it's not a big deal. If that is the case I can't understand why companies are spending millions trying to get the response times down to 5 and 4 ms. Can the human eye see a difference with ghosting etc?
