Hz is related to the TV's refresh rate, More hz = better for fast moving images. It really won't have so much impact on live TV as the method of filming is a limiting factor.
Tube Tv's have a refresh rate, it's just not advertised. Current LCD TV's can hit up to 120hz there should be no detriment to your picture especially while playing computer generated inputs(games PC etc.)
I'd actually pay more attention to these factors: Dynamic Contrast Ratio, Contrast Ratio, Brightness rating, Backlight type, and Response time.
