Anti aliasing Question.

I run a 24" monitor at 1920x1080. is 4AA more than enough at that resolution? is 8AA not work it?

The higher the resolution the less you tend to notice the jaggies. I would say 4xAA is perfectly acceptable.

Depending on the card a person may have 4xAA may make afew games chug a little... in that case I don't think 2xAA is a huge drop in image quality either at 1920x1080 or above.
 
Tbh the question is what do you think?

Each game generally implements and is affected by anti-aliasing differently. Sometimes there are big trade-offs to be had. For example, Crysis framerates are infamously slashed by antialiasing. Or as another example Neverwinter Nights 2 becomes horribly blurred once AA is activated at all.

The best advice I could give you is to play with the settings on each game as you play them and see what appeals to you best, given the performance weighed against the visual quality you get on your monitor.



...If in doubt and in a rush though, 4xAA should suit most people fine, especially at that resolution :p

As Alex 74 said above, it's your choice. I generally find 4x is fine on my 24", the only decent increase past then (IMO) is 16xAA (with all the extra AF FF FA or whatever it's called).

Play around and see what you think is best.
 
I would say 2 or 4 is fine. I don't always bother with AA since at higher resolutions it isn't that bad, game dependent and down to opinion of course. Jumping from 4 to 8 is one heck of performance nose dive for most systems when running a majority of games.

4xAA & 16xAF is fine for the most part but others I ramp it up when I have some leftover power, ie. GRID 8xMSAA, Street Fighter 4 C16xQ etc..

It varies with the game, but I usually find 2x is enough. Like rounddodger, I'll ramp it up if I can (and I usually can with the 5850), but hand on heart, I can't say I've ever spotted differences above 2x. Even 2x isn't always necessary. I never missed the lack of AA in Batman AA (Batman Anti-Aliasing???)
 
It depends how it is implemented and how keen your eye is. I can generally tell the difference between 2x and 4x @ 1920x1200 but not so much between 4x and 8x. 2x is normally more than enough for me, until recently I never really rolled with AA since trying it in the GF2 days warranted enough of a performance drop for me to consider it worthless (until recently when i tried it again of course)
