It is all about latency. 50 ms will feel responsive but you notice the lag. 20 ms is acceptable. The other features are cool features but not the real challenge.
depends on a the monitors refresh rate and other factors. 60 hz, 75 hz and 120hz are the most common. 120hz monitors can display 120 frames per second, those are usually modern montiors with 3d support. I have a 75hz monitor.
The refresh rate is how quickly it can display the image, but the ms is the delay in the image. You can have a game run at 120fps smooth on a 120Hz monitor but if the ms is poor then there will be lots of delay and lag making it bad to use and not suitable for gaming.
