I play quake on 2 years old, 19" widescreen with 5ms response time and 62Hz refresh rate at 800x600 resolution.(it's the shittiest monitor ever I know. I didn't even know that quake exists when i was buying it..) So how much of a difference does 120hz make? I mean, if I go into LG battle with someone that has 120hz refresh rate, how big is his advantage?
