At this time I have an i-5 4670, a GTX 660 graphic card with a 650 watt psu. I would like to upgrade my monitor to a 27/28 inch 144Hz model. I have a HP 2511 monitor now. The 60 Hz is alright most of the time when I play WOW but in 25 man raids the picture quality suffers on the highest settings. I would appreciate some input before I lay my hard earned $$$ down.
