FWIW, the "e" monitors that Dell carries are their lower end models, and usually not as good for gaming as their higher end models.
My father uses a e173fp and it is ok, but not great. It has a waving effect that is notceable. As I said in the other thread though, the 1800, 1901, 1905, 2001 are all better IMHO. As someone mentioned, not EVERYONE will think they are great for gaming, but in general they are much much better gaming monitors.
If you just want a decent monitor and play occasional games, it might be a good deal. If you you do any serious amount of gaming, I'd save up for a better monitor.
