i would prefer a monitor with high resolution monitor for gaming more than high refresh rate one,
my suggestion would be Asus Pro Art series ( PA279Q http://www.asus.com/Monitors_Projectors/PA279Q/ ),
but !..... if you want a gaming grade monitor with 3D, 144hz refresh rate, and that stuff, my suggestion will be BenQ XL2420TE http://www.benq.ca/product/monitor/xl2420te,
but it was 1080p unlike the PA279Q with 1440p resolution ( but 60hz and no 3D )
Note : Linus have an unboxing and reviews for both monitor ( just search in youtube )
