After Catalyst 4.9, I still get the same framerate I did in 4.8, but the image quality is much better in Doom 3. I see allot less jaggies even with no AA. I haven't tested it out on other games yet, but hopefully it improves Far Cry as well.
I also notice that instead of instructing your monitor tube (if using a CRT) to change resolutions, the card itself is changing resolution. I used to hear a clicking noise when the tube was changing, but now it's nice and smooth.
