Samsung 8000 vs 7000

[psx3man]

How is the picture quallity on the 8000 vs the 7000. I know the 8000 has the real black filter but what does the 7000 have. Is the picture alot better on the 8000. And i allready know the panasonic a better picture so theres no need to bring it up. I was thinking of getting the 58 inch 8000 right now at amazon its $2366 and the 63 inch 7000 is $2650. Sould i just stick with the 8000 or switch to the 7000. I found this on samsung website.
