Thanks tt,Do you have transparency on in your "windows theme" settings - older versions of Maya used to really hate it for me - something about being able to see though the top bar drove it nuts.
It being a gaming card means nothing - its mostly cards with good opengl settings that are better - had real problems with displays and ATI in the past but I`m not getting in to that fight again (I hate them - FYI).
Anyway turn off transparency under color in the theme settings and see if that sorts it for you.
