I personally always go with a new display unless I know who I am buy it from. I do not know your situation is or what a new display would cost you, but I am a huge fan of the Dell Professional and UltraSharp displays. I dislike their consumer end because they feel cheap, just like HP and all the rest. Out of those two, I'd take the UltraSharp any day. However, if a new display isn't much more I'd shop around. Just remember the UltraSharps us an IPS panel and they have better color than a TN panel. They are also inherently slower than a TN panel, but most IPS panels made within the last few years are perfectly fine for gaming.
