The biggest difference should actually be in movies, not games, as most games are coded with 60 fps or 30 fps in mind. it's the video cameras that take 24fps that makes the problem. with a 60 fps tv it has to do all the 3:2 pulldown and that jazz to make the picture appear smooth. my TV doesn't have the 120 Hz so I can't vouch, but I did see a Sony LCD the other day in Circuit City with a Blu Ray player playing Night at the Museum and all I could think was "wow that looks like I'm looking through a window." Maybe it's the quality of the TV, but I assume that 120Hz had to have something to do with it's smoothness, because I watch a lot of Blu Rays and I've never thought it looked that smooth. I guess the question is how much of a premium it is. I'd like to hear from someone who has one of those TVs in their house though.
