Will there be any issues port wise? I figure two of the monitors can use the DVI-D (I think they're dual-link, not sure?! :/ ) ports, but I think the HDMI and DVI-I don't support 144hz and am not sure if the Display Port can support 144hz.
I don't think hdmi will support 144hz, but DVI-I is a superset of DVI-D so it should be fine, and Display Port has the most bandwidth and supports 144hz.
