1) Is this video card better than imac?
no, the 680mx is still way better

2) Is this screen any different? How does this new screen compare to the imac?
according to reviews, the screen is pretty glossy - the new iMac has a layer to help cut down on reflections. i'm currently using in a sunny room and have no problems.
touch screen is pointless. it's a gimmick. if it's in the living room as you suggest, you're probably not sitting close enough to touch it.
if it's on a desk, then gravity is your problem. why would you want to hold your arm up all the time when mouse and keyboard work so well?
and finally, all those lovely finger marks on your glossy screen? those will look just great.
3) Does this change anyone's mind?
no.
no, the 680mx is still way better
