^^ Who said that they aren't meant for gaming? Ips panels are considered the most superior of all lcd panel types not only for viewing angles but far better colour reproduction with a wide spectrum and better light scattering matrix.
Ips panels previously were plauged with poor response times but now have significantly improved making them ideal for gaming usage.
So you can definitely give that lg a good look. I have an LG ips hdtv (32 inch) and i have played battlefield 3 and modern warfare 3 on it. No ghosting effects at all and it looked so different compared to my 20 inch samsung TN monitor. The colours were vivid and more natural. So you can definitely give that lg a look and probably test it out before buying.
