I kind of like my VA for gaming. It has 4 ms reaction time and good colours, and I don't need more than 60 fps, hence refresh rate. But competitive FPS (or even competitive something else) surely would be a different matter, not that you can't do competitive gaming on 60 fps.
The BenQ have good reviews.
In any case, I'd probably insist on trying them out first or at least seeing them at work, first-hand.
