Is there that much of a difference between 120hz and 60hz? Is it worth the price difference? Our kids use Wii, but otherwise aren't big gamers, which is what I heard 120hz was best for. We're looking at Samsung 46 inch LCD or LED and thought 120hz was the way to go. Heard from some people that there isn't much difference between 120hz vs. 60hz. Looking for some feedback to help in our decision. Thanks.
