I think you should go for either the Acer XFA240 or BenQ Zowie XL2411P, they're both 1080p144hz with low response times
the BenQ one is a bit more expensive but it also has some anti motion-blur technology. I've personally only used the BenQ one and it's definitely as clear as a 1080p monitor can be, the only downside is that you probably need to fix the colours when you first set it up as they're usually pretty bad out of the box
