Just got conformation that my Alienware Aurora R3 has just shipped, so now need a good monitor to go with it. Of course being that I just ordered an Alienware I don't have a lot left to get an optimal monitor. Any suggestions say in the 20" range? I am thinking LED backlit but finding one with low enough response time <5ms, preferable <3ms that is still affordable is tricky. All the reviews say <3ms, but does anyone have one with a 5ms response time and do you notice ghosting problems?
