I currently have two 23" HD (1920x1080) displays, but I am feeling the need for more screen space (and some shiny new IPS displays).

I am in a dilemma as to if I should get two 27" WQHD (2560x1440) IPS displays, or three 23/24" HD (1920x1080) IPS displays.

I am a web developer working from home, so I spend quite a bit of time doing work and gaming (along with general browsing).

Assuming the displays are of similar quality, then which would be the best setup?
