I find it to be fine, there's no visible ghosting and so on. It is true that the panel type is more focused on image quality over reaction time, but that doesn't mean that reaction time is actually a problem. I do play a lot of fps on it.
i simply love it
the only thing is that it really requires some gamma tweaking, it is WAY to high by default - i was actually a bit scared when i first turned it on. but after reading some forums i realized that its a common problem with some of these mons, lowering gamma settings with video card control utility (mine is ATI control center) makes this monitor looks really good.
in fact, both static and dynamic picture wasnt really better on my pretty old but semi pro level 17" tube.
