I own the Benq, you have to set it up right as out of the box the picture is terriable. But, when it's setup it's very good - almost no input lag and 120hz is good, you will need a graphics cards that can handle 120 fps.
I've not suffered with light leakage or dead pixels
Yea, I think my 470 may be up for it in most games (may need to tweak a few settings though and overclock it.) So, nothing bad to report from the BenQ?
