The 144Hz Asus looks great. Watch the VIDEO at 1080p fullscreen. Link again:

*In the video you can see he could choose 60Hz, 85Hz, 100Hz, 120Hz or 144Hz for 1920x1080.
The 27" version above costs $100 more, however I'm not sure if you'd want a 27" screen with "only" 1920x1080 as you tend to be able to see the individual pixels. I haven't seen that model up close. I suppose you could just MOVE IT further away if that bugs you (which would then be the same as the 24" closer).
**Can input HDMI and output audio to desktop speakers for movies/games etc. I tested this with my GTX680 on my U2711 and it works great. I haven't compared audio quality versus onboard or sound card but it sounded great to me and I'm picky (assume it's decoded on the graphics card but not certain).
