I would not recommend older models like the GN276HL due to lack of DisplayPort connectivity. Older 144Hz monitors without DisplayPort can only do 144Hz over Dual Link DVI. This is going to become a problem in the near future as DVI is starting to get phased out on newer graphics cards, most new AMD cards don't have DVI anymore. You can get around this problem with an expensive active adapter, which costs about $100 but at that point you might as well just spend a little extra to get a 144Hz monitor that has DisplayPort instead.
