i was about to get a 25.5inch 1920x1200 screen and iv heard that games dont even need AA at that resolution is this true?
 
My 24" 1920x1200 Samsung 245bw looks good without any AA, however things still look better with AA turned on, especially older games like Quake Live and Counter Strike Source.
 
how far away you sit has an effect as well. there is a point where you can have too much resolution for your eyes. aa is only for when your eyes arent getting enough resolution

imo.

anisotropic filtering will have a more significant effect at higher resolution.

again imo.

hmm,didnt know that.
 
At 2560x1600 on my Dell 3007WFP-HC, AA still helps a lot, it's a little better than my old 1680x1050 resolution and 1920x1200 ones were as far as AA being a MUST for it not to look bad, though. Whereas I wanted 8x AA on my lower-rez panels, I find that 2x-4x works decently on this size.

No, it's to smooth the color gradients between two harsh edges... even with resolution beyond what you can reasonably discern for a given seating distance, it helps significantly.
 
AA also helps remove interference patterns as you move.

ie when looking at a distant metal railing, its impossible to draw every photon as the resolution doesnt exist on your display.
So as you move, the perspective changes and so does the representation of the railings bars, thus giving you one pixel (wide or high) jagged edges.
The metal bars end up jumping into/out of existence (on screen) and can create a moving interference pattern.
You can also get interference patterns when 2 almost see through objects move past each other or as an edge of an object passes another object.

Interference pattens also occur in real life and that is incredibly higher resolution in comparison.
However, being such high resolution, real life doesnt look as jagged.
So to look its best not in real life, you need AA.
