I'm thinking on buying a new monitor, so far these are my options:

http://www.amazon.com/BenQ-RL2455HM-...=BenQ+RL2455HM

https://www.amazon.com.mx/BenQ-RL275...ywords=monitor

I'm also planning on doing a double/triple monitor setup (but only gaming in only 1 of them)

And of course, I'm looking for a monitor useful in FPS like Doom, Unreal Tournament or Quake Arena.

Finally, that is not very expensive, something between 150USD and 450USD.

Thanks in advance.

P.S Any grammatical error please let me know.
