My HVAC guy says that 95% vs. 80% takes years to pay back. All else being equal, you will save maybe $50 a month with the 95% vs. what you have now, for the two or three months per year that you really run the furnace extensively.
Also when you move to a 95% furnace you will need to run 3" PVC exhaust and combustion intake pipes out the side of your house somewhere. We have a Carrier 95% furnace and it's a major pain. Gets into cycles where it won't want to ignite, then it goes into a 4-hour lockout mode before it will try again unless you cycle the power off and on to reset the computer. There are more sensors and control devices on the high-efficency furnaces, which are more things to go wrong. Maybe we just have a lemon, but I'd do some research before you buy.
