Competitive gamers usually use 60Hz refresh rates because there is less processing therefore less input lag. But 120hz+ is much more pleasing to the eye with fast movement and regular browsing, just feels much more fluid. TN is also a better way to go if you like twitch games and etc, these generally have faster response times. IPS is limited to 60Hz (in exception to Overlord Tempest & Yamakasi 2B) but will offer way better color production giving you a much more immerse experience. If I were you spend the extra dough on the video card and get a simple LED 60Hz 21"-24" gaming monitor. Asus, Dell, Viewsonic, and Benq all make one. Some people underestimate Dell monitors, but they have some of the lowest input lag
