depends obviously how you look at it. sit in a small room close to your 50 inch tv and you will see it. sit in a normal living room with a table and some room between the tv and the table and you will probably see not much except for the better anti-aliasing.
with a 60 inch tv you will also see some difference even with some room between you and the tv. with a 32 inch tv you will probably not see a difference on your tv even without much room between you and your tv.
much more important is that they added better anti-aliasing. that's at least what they said and that is something most people will notice even without noticing how sharp the picture is.
the thing is, if you compare these pictures side by side you see it. if you will play one version today and the other next week you wil probably not know which was better if someone would ask you (i would bet that this would be the case with 90% of posters in gaming forums)
