Audioholics has an interesting take on 1080p graphics - you may not be able to tell the difference between that and lower resolutions in real-world settings.

Warning: long load times due to their very annoying ads.

The resolution of our eyes is 12 vertical lines per arc angle (one line per arcminute for 20/20 acuity) times 2. Now 28 degrees x 12 lines x 2 = 672. This means we really can't see a display component (pixel) smaller than 1/672 x image width. Our minimum resolvable element size is about 0.065", or about twice the size of the pixels of the WXGA image! Put bluntly, from 8 feet away while watching a 50 inch plasma TV, the human eye is generally incapable of reliably distinguishing any detail finer than that shown on a true 720p display!
