I wanted to jump to 2k but decided to cheap out and just get a nice 1080. Ended up buying the ASUS VG248QE 24" 1920x1080 144Hz 1ms for $204 shipped

The one I ordered just arrived today.
My first impressions are.
When you first power it up you will probably be like me and like it. You should do a search on setting this monitor up. You will find many suggestions.
Here are the settings I am starting with and so far I like them.
Splendid- theater
Brightness 100
Contrast 83
Saturation 42
Colour temp User mode - r-83 g-83 b-83
Skin tone natural
Smartview off
Sharpness 50
Tracefree 40
ASCR on
Nvidia vibrance set to 50.
eco mode off..
Coming from a 60HZ moving to 144HZ was like night and day.
I am running it behind an NVIDIA 960 4GB card.
Not changing any settings other than moving to 1920 x 1080 resolution it runs AH fantastic with very fast frame rates. The detail that you now see is breathtaking.
The look and feel is so much different than at 60HZ. The movements of the plane are much smoother also the instrument panel is clear and sharp.
Good luck with yours you will like it.
