I got
this monitor for Christmas, and it's amazing (same price as the ones above). I haven't had any problems so far with it, the only thing you need is a dual DVI cable (which comes with the monitor) and the ability to run games above 60fps.
Also, in CSGO (any game, really) there is an insane amount of difference between a 60hz and a 144hz monitor, and you can feel it.
