Well I care about nvidia 3d vision. As soon as a 24" 120hz I am going 3d. Have you ever been to a new 3d movie at a theater? It is freaking cool. You have to remember that hundreds of games support nvidia 3d and and a whole lot of movies too. It isn't just for games. It is certainly MUCH cheaper then going to the theater a lot and paying for the expensive food.
Physx is BY FAR the greatest physics engine for PC and console. I guess you never played any of the really good physx games/tech demos. You also haven't seen the fermi physx demo either.....
It is in 3d so it is blurry to us.

Oh and DX11 ya when are any good games coming out with it? Not this year. Dirt2 and Battleforge don't FULLY support DX11 yet. It is just a patch like Company of Heroes is DX10. So it is bull to say they are DX11 when they merely added like 2 features long after it was in the works. You wont see full DX11 games for awhile because it hasn't been fully released to game developers and it takes many years to make a game. I think this is the time we will see some very good DX10 games by now because DX10 has been out long enough for games to be made from the ground up on it.
Oh and ATI's cards are faster for now but they are only a small increase. So it isn't something I would go crazy over. Also we don't know the performance of ATI's cards in DX11.
