help needed in lcd purchase

[ultimate11]

i currently have viewsonic vx2235(5ms) and i was thinking of buying another so i would have dual lcds so it would be fun playing wow.
my use is gaming + surf + movies


i have the following choices:

viewsonic vx2235(2ms one)
viewsonic vx2255
samsung 226bw
samsung 2232bw(hopefully its samsung made)

thats all i can get for now which one should i go with

i read about the new upcoming samsung 2253bw but i dont think we will be getting it any time soon here in Pakistan.

thanks.
