Looking for real world experience of these monitors, 2560x1440

[Fisher]

So six years since I last bought my BENQ FP241WZ 24" and think Im in need of an upgrade. In a nut shell needs to be:

27”
2560x1440 resolution
Price: Not that much of an object but there is a line
Use is for gaming and internet browsing

Games such as BF4, Batman Arkham Origins, ROME II, DayZ – I am an eye candy whore so max settings all the way

Current setup is
Core i7 @4.6mhz
SLI GTX680s

This last week I have been reading and debating with myself 1440 vs 120mhz and im coming to the conclusion that I want the bigger resolution with the more accurate colours

I understand that some monitors in this category are meant for more professional working and may have motion blur, lag and overshoot. However I have read a lot of mixed reviews with some reviews saying there fine and others not.

What I want to ask is: Does any one on this forum have any real world experience of these monitors in reference to gaming such as ghosting or overshoot? Which one is less painful in respects to this?

Samsung S27B971D - a little past the line in terms of price

Asus PB278Q – looking at this one mainly
