I have managed to fix overscan problem by creating Custom resolution 1920x1200x60Hz using DMT, but sharpness was a bit off and I could not adjust it using monitor controls.
Then I said to myself - lets try 3870 instead.
Have installed card, downloaded Catalyst - and everything is perfect
My dislike to NVidia is deepening fast. Now they cannot manage a monitor resolutions properly, not a TV panel.
3870 is FAST - any game is just flying.
