Response times are variable to say the least. One company will measure the time it takes for a pixel to go from black to white to black, for example, and another company will only measure the time for black to white, and so on.

Best to read reviews and use your eyes. What you see is what you get.

Are you getting ghosting with your screen now, fast moving graphics not keeping up with themselves? If so, you will see a big difference at 2ms.

I have a 19" Viewsonic VX922. It has a listed 2ms response time and got good reviews. Decent price too. I mostly fly flightsims and have never experienced any ghosting or image tearing even when things get fast and busy on-screen. Other games like M:TW run very well and look great.

The only downside to this screen is that movies don't look as good as they could. Animated stuff like Finding Nemo look fantastic, but ordinary movies look a bit blah. Good, but not outstanding. As a game screen, I'm loving my Viewsonic. Wouldn't hesitate to recommend it.

Some other people here really like the new Samsung screens. Not sure which model.
