See the chart.

Sorry, no that's not correct.

The 80 Plus standard is the efficiency target -- as in 80 per cent or more of the energy pulled from the wall by the PSU is delivered to the computer. It's named for the expected efficiency at 20 per cent load. The standard sets minimum efficiency levels for loads at 20, 50 and 100 per cent of the PSU's capacity.

80 Plus Bronze, Silver, Gold and Platinum set progressively higher targets for the PSU's efficiency.

Whether it's worth the extra costs depends purely upon your application. Figure out how much electricity you use, how much less you'd use with a more efficient power supply, multiply the difference by the cost of electricity in your area, and compare that to the premium of buying a more efficient PSU.
