Vsync limits your FPS to your monitors refresh rate.
You just have a bad graphics card because it is unlikely that your monitor is running at 40Hz

ALWAYS Hide modes your monitor cannot display (little checkbox).
But the higher your monitor can go, the better.
(On a CRT monitor) 75-85Hz is a good refresh to go for, 60Hz will give you a headache.
(On an LCD monitor) 60 Hz is the norm bwcause they refresh differently. Don't go higher.
