NEC MultiSync 24WMGX³ vs HP LP2475w vs BenQ FP241W

Hey everybody,
for a while now I've been looking for a 24 inch monitor primarily used for gaming, movies, some office work and photo editing.
Of course you can't have everything in a monitor, however I'm looking for one that can handle everything pretty well. Since I do enjoy fps games there can't be a lot of input lag, on the other hand I don't want to sacrifice to much image quality. 600$ would be the limit.
I came up with a few:

NEC MultiSync 24WMGX³

HP LP2475w

BenQ FP241W

Gateway FHD2400

I'm open for any other suggestions, however I'd appreciate some feedback on the monitors I mentioned.
Thanks a lot in advance ;]
