Actually you are all wrong.
First of all the eye doesn't perceive motion the brain does.
Second of all the brain begins to perceive motion at around 20fps.
The average brain cannot descern anything above around 100fps. Its quite possible depending on image size some people may be able to descern higher frame rates.
Around 75fps is the magic point for losing 'flickering'.
Finally, "eye doctors" know stuff all about this as it falls into neurology.
How do I know this stuff? Well I suffer from a neurological eye 'disorder', non-binocular vision so its always been of great interest too me.
Oh, and mrblack what are you sure your monitor handles decernible 1600x1200 with FSAA? Check your dot pitch and you'll probably find you are throwing away GPU cycles on FSAA you cannot see (except in framegrabs displayed in lower resolution).
