As 97% of us now have LCD monitors, AA does make a decent difference when enabled, so now I ask how much AA do you need to have nice image quality while keeping things running smoothly? -I'm personally set with x2 AA, anything else i believe is just a waste since the rough edges disappear with only x2 AA. Anything more and it only makes the edges "thinner" per say. Then again the max resolution i have ever played at was 1680 X 1050. I dont know the difference, with anything higher than that.
