I just received my Alienware OptX AW2310 this week. I was looking for a bigger 120Hz monitor but I didnt trust Acer nor could I wait for Asus or Viewsonic to release theirs.
Overall I'm pretty happy with it, 120Hz is awesome...running games without vsync there is absolutely no tearing, running games at 60Hz, vsync and triple buffering days are over.
I'm not really that interested in 3D, though I might look into it later. I just wish it was a little bigger and a better panel opposed to a TN.
Overall it gets 8/10
