I currently have a 60Hz TN Acer H235H, which is a great monitor, but so much more is possible.
I can't make up my mind whether to choose for a 27" 2560x1440 or a (~23) 120Hz display.
To power the screen I am using a GTX670 windforce 2Gb.
I will use it to play games like League of legends, GW2, Skyrim etc.
My budget is about 600 EUR, and I absolutely don't want a glossy screen.
