Well I could get a 300$ viewsonic 120hz monitor and use the polarized glasses I got from the movies, but then I wouldn't know how to set it up to show 2 pictures, the nividia one does it all for u. ( and the glasses looks cooler lol )
Or If I fin my old blue and red glasses I can use the nvidia drivers to see games in 3d but it would come out with bad color and blurry during high action scenes.
I'm just waiting for the sony monitors that run 3d in the hardware so all you need are the glasses, doesn't matter what software or gpu you have.
