Do note that AA sucks on some cards because it needs LOADS of extra VRAM and if you don't have it then what follows is massive stuff swapping over the AGP. So if you have old card with say 32mb of VRAM, AA probably sucks (and the GPUs are already slow and ancient), and upping resolution with AA just consumes more VRAM. Use low resolution if you need to use AA.
And I agree Anthony - I'd rather have AA'ed 800*600 ANYDAY over sharp 1600*1200! 1600*1200 does make jaggies go away without AA somewhat, but it makes everything too sharp and pointy IMO, as generally speaking texture are not designed to look good in that high rezz. And there is this FILLRATE problem creeping in too; it get BAD very easily when you are using high resolutions.
My ideal (default in my own game) resolution setup is 1024*768*32 and AA if you have fast card for it like new Radeons.
