True but there's usually still enough performance left over depending on the resolution.Before you say it, even Nvidia cards lose performance with AA on at super high resolutions with some of the newer games.
Also IME 4xAA should be a mandatory minimum as it increases IQ far more than the associated resolution raise (i.e. it's worthwhile to drop the resolution to get it).
That and CRT users can lower the resolution. I run new games like Bioshock and MoH:Airborne and they're perfectly playable at 1760x1320 with 4xAA full details (except I reduce post-filter effects as they blur things too much and I hate that).Let's not forget not everyone has 1920x1200 capable monitor.
