That should be good for F.E.A.R., but don't expect resolutions higher than 1280x1024.
You kidding? My system easily runs FEAR at highest no AA/Full AS filtering/no soft shadows @ 1280x1024, that's with a 6800gt...
Why buy a high end card if you can't use antialiasing? I use 8X for most of my games, and 4X for a special few, such as Age of EmpiresIII and F.E.A.R.
I think higher resolutions > AA in image quality.
