The ASUS is better for gaming, if that's what you are planning on. But I do believe there are better options out there, especially with the contrast ratio being 1000:1. I'd most definately keep an eye out, considering that there are going to be tech deals on monday at most stores.
On a side note, for monitors, size does matter. With bigger screens, you get more productivity. This is why people go with dual monitor displays. Just some helpful information.
