Choosing a new monitor for my build

Hi all,

 

I am looking to purchase a single new monitor I am looking to spend $400 (soft budget) and $500 (limit) and currently located in Australia. Currantly I am using 3 Dell E228WFP 22" monitors (http://www.cnet.com/products/dell-e228wfp-22-widescreen-flat-panel-monitor/). I am planning on using the monitor for gaming, cad (solidworks) and photoshop (sometimes).

I am running sli 660 ti, I7 3770k, 16gb of 2400mhz ram and raid 0 ssds

so higher resolutions or taking up higher refresh rate should be less of an issue. Currantly I have been looking at the

x-star DP2710 or simmilar (Korean, 1440p, A- ips panel)

Dell U2913WM (21:9, ips)

ASUS VG248QE (1080p, 144hz, TN panel)

 

seeing as I have got myself stuck in a loop of which I want too get any help choosing would be greatly appreciated.

 

Thanks,
