Why does my car over heat?

I have a 2002 Honda civic ex I have had the radiator, water pump, timing chain, and thermostat replaced in it recently. However when ever I drive it over 50 mph it starts to over heat and water is spraying out of the radiator through the top were cap is at. I can drive it all day under 50 mph and it is fine so does anyone have any ideas to why my car is doing this?
