27inch monitors, what to get?

Looking for a 27 inch monitor Its for mostly gaming. Lots of bf4 but also a range of other stuff like saints row, castlevania los, batman or whatever else thats good. Also i play codemasters racing games like grid 2. So basically everything that isnt wow or dota Anyway, im not sure what sort of monitor to get. Do i get the asus vg278qe, 144hz fast response time but not great colour or view angles because its tn panel. Asus mx279h, a good quality ah ips panel so good colour and angles Or dgm ips 2701wph, 2560x1440 not sure if pictures any good beyond resolution but its the cheapest high res i can find

My budget is up to £330 ish. Give me any other monitors that maybe better but basically i dont know if i should be looking for hz and response time, high quality picture ips, or high res. Currently i use a 32inch lcd tv thats 6yrs old and the pictures not great plus response time is high because its a tv so any monitor is a step up from what i have.
