Like I said, Anything above 4x is really unnecissary. Heh, I have to play these new games at 1024x768 with no AA or only 2x because my card can't handle it. And with Doom 3, It struggles even at 1024x768 resolution. To be able to just play Doom 3 smoothly on 1024x768 would be awesome, let alone on 1600x1200.
