Reason I ask is I prefer what I hear, and prefer the matte screen of the BenQ 2420's to Samsung's 120 hz/3d answer. However based on my game preference the 7970 often-times beats the 670 and is similarly priced so there's a fair chance i'd end up with an AMD GPU.
So... will the monitor still perform admirably/optimally with AMD GPU? Also will I never be able to use the monitors 3d capability? That could be a big deal because i'd like to try 3d gaming. It'd be such a shame if that monitor just isn't as good with AMD
So nice, 120hz, 3d, little bleed, nice response times, good colours for a TN and nice connectivity options too (USB slots too 
).
