I bought a Hanns G 27in that was rated at 2ms. It had bleeding problems with tags, the beach, the moon etc.
Then I got a 27in Samsung from Costco, better but still some issues.
Finally I bought Samsung S27A750D 120hz 27in with 2ms (gtg I know, TN not IPS but the best TN panel out there)
The difference is night and day. The game looks incredible on it.
It also does 3d although that's not why I got it so I haven't really messed with it much.
The only issue is it requires an ATI 5000 series or higher with a display port for 120hz.
It only has HDMI and display port connections.
I read once long ago when I started overclocking to go out and buy the best monitor you could afford before you buy anything else. Somehow I forgot that, being an eye candy guy I'm not sure how.
This monitor has changed my computing experience 100%
Find a 120hz monitor you like and you wont be disappointed. Or wait for OLED, but thats a different matter, and big $$$.
