Should I buy a new furnace to save money?

A standard efficiency furnace provides 80% annual fuel utilization efficiency (AFUE). In this type of furnace, 20% of the energy produced by natural gas is expelled as exhaust. High efficiency furnaces offer 90% or more AFUE. These days, 95%-97% AFUE is a common rating among new gas-powered furnaces. Only 3%-5% is wasted as exhaust. So, a 95% furnace is more efficient than an 80% furnace. It should be a simple choice, right?
