I am looking to buy the 55d7000 while the d8000 is also available for an additional $500. I have done some research and found the only difference between the two was clear motion rate (which is not the native motion rate), both are 200 Hz but the 7000 has a CMR of 600 Hz and the 8000 has 800 Hz. Will it make any real difference on the 55 inch screen ? Will it be visible on the large 55 inch screen or not ? If not, then I would go ahead and buy the 7000 and save some $$$. I haven't been able to compare the two side by side.
