I run BF2 at 1280x1024, 4x AA, with all but 2 settings on high (can't remember which ones) with 1GB of RAM, and I get ~30-35 FPS. I used to run it at 1024x768 with those same settings, and I got 50-55 FPS, but since I got a new LCD monitor and the native resolution was 1280x1024, I decided to try it out. I don't actually notice much difference in FPS when I'm playing, except in artillery explosions, then I've noticed it hit as low as 13 FPS. I was going to change it back to 1024x768, but I keep forgetting and it doesn't actually bother me that much.
