Should I be playing my games at 1280x1024 (75 Hz) without 4x AA and 8x anisotropic or @ 1024x768 (100 Hz) with 4x AA and 8x anisotropic on? I can go to 1600x1200 but my refresh rate only goes to 60 Hz at that res. I feel that I need at least a 100 Hz refresh rate so I've been playing all my games at 1024x768 with all the goodies on.
