I've been looking for a good 1080p monitor, 24 - 27" 120Hz and desent response time. The only really good monitors I know of that are like this are the Asus VG248QE and the Benq TX2420T, if anyone can offer any recommendations it would be appreciated.
Get the Asus VG248QE, I have one and love it.
My performance in Unreal Tournament skyrocketed after getting that monitor. Also check out 2D Light Boost.

As far as FPS games go, I think BenQ's XL2420T is one of the best. I had it for a week, and it was amazing. Never tried the Asus VG, though. It could be better.
Ya I have heard the Asus 144hz with lightboost on it the way to go if you have $250 for a monitor but you will need nvidia card for lightboost. But I am sure it will do fine with out it too. The BenQ monitors are nice too with the black equalizer.
this is a really solid monitor. i recommended a friend get it, and he loves it. its an update to the 'EVO' (evolution tournament, or EVO, is the world championship tournament for fighting games) monitor. same panel, only its LED backlit.
it has very low input lag. half a frame. this is key for FPS and fighting games.
