Dell Ultrasharp 2711 still worth it in 2016?

So I have an offer to buy a 2711 1440p monitor, but from my understanding they where produces in 2009 which is quite some time ago.

I currently have a 2713HM but it has two dead pixels which is why I'm looking to buy this one, would be worth while? since 2009 IPS was still a new tech.
