I'm rocking this setup right now, and honestly i love it.
I cracked my old LCD while painting and decided to replace my old VA type LCD with with a good gaming LCD. After doing a bunch of research, I decided on a 120hz TN, as this would be the optimal performance for gaming. The logical choice from there was the samsung 2233RZ and i'm very happy with it so far. The 120 hz performance is really amazing and very noticeable.
I found this thread because i'm curious if there are any known problems with this technology running under windows 7, i'm currently running vista 64 and am hoping to install windows 7 very shortly.
