People, you need to see the links, not the photos at the OP, because you won't notice the difference, if you see the links, the difference is quite noticeable, much more than i expected.
In the second one you only need to take a look on the buildings on the left. The 900p one is a lot blurrier than the 1080p.
As I've said, I didn't expect so much difference between 1080p and 900p, but in a full HD tv of 42'' o 46'' it should be quite clear. This confirms too, that people that don't see the difference between 1080p and 720p of the same game are more than blind....
