Depends on the game. 720p @ 60fps for racing, fighting, and any other type of game that requires quick, precise reactions. 1080p @ 30fps for everything else.

why would you need AA in 1080p? if the game is build with that resolution in mind and that is the higher resolution of your screen, no AA is needed... AA smooths edges with intermediate pixels but in max resolution there won't be intermediate pixels as they are all in use by the native image.

@on-topic
if real steady... 30 fps is enought... what bugs me is screen tearing and fps drops, get that out of the way for the next gen and i will be happy...

Edge flicker and other artifacting can still happen.  If there was no benefit, then PC games wouldn't have an option for 4xAA on native 1080p games.  It's beneficial for everyone, and especially for people like myself that see aliasing easily.

Anti-aliasing just blurs things for me. Even on my 720p monitor I leave it off for some games, sharper and more FPS. I can't imagine adding AA to a 1080p game.

The frames.

Just gimme the frames!

Framerate over resoultion. I don't care how gorgeous you are. If you run at 10fps, you can't play it.

1000fps @ 320x240 @ 256 colors

depends on the game. If it's really fast paced like a twitch shooter than 60fps, if not than I'll take the better resolution because I hate jaggies and 30fps is fine, and looks perfectly smooth with motion blur.

There's more to it than just higher resolution. A higher resolution will make your image more crisp and help with jaggies, but when all other things remain constant, graphics will remain largely unchanged.

With that said, full 720p at constant 60 frames per second would be more ideal.
