Why blender won't show transparency in the 3d vies' bars?

Hi guys I’ve got this doubt. I’m currently using blender 2.76b and blender won’t decrease the opacity of the tool shelf and the properties bar. I have turned the show header and show background options on and set the alpha for both at zero but nothing happens.

I have a Geforce gtx 760 graphic card. is that it? Should I get a newer one?

Thanks guys

Have you enabled the ‘Region Overlap’ tickbox in the User Preferences / System panel
The window draw method also needs to be set to ‘Triple Buffer’ or ‘Automatic’
