they quote 3.4 ms response time on an ips , which I would have to see to believe. Also what kind of ips? there are several cheaper variants now. Another question is, is it only 60hz ? It would need to have a very low response time (2ms - 3ms) , 120hz input, and aggressive Response Time Compensation / overdrive to compare to a gaming TN that has all three. This still wouldn't compare to essentially blur free / lack of FoV movement scene-smearing fw900 of course.
Gaming display with no advertisement as 120Hz? I must be missing something.
