I have a 50 yr old gas boiler. I use gas for heat, hot water and clothes drying. My monthly bill averages $100. If I replace the boiler with an 80% efficiency boiler will it be cost effective.

If I buy a fish tomorrow will it be able to feed the people I'm having over on Friday?
You have not given enough information to give you an intelligent answer. You need to answer how many people are using the facilities, how cold your area is, how efficient your house is, how many showers or baths are taken in a given period of time, how much water is heated and on and on.
There are a few people here who are good at making estimates of the heat loss of a house when they know the size and style of the house and the approximate age of the house. There are standard assumptions that can be made concerning the amount of water used by a specific number of people living in a house.
The problem is that without hard data it is utterly impossible to state with any certainty that some action may or may not be cost effective. Heck, even the term cost effective is subject to interpretation. Do you have a large pile of money in your garage to spend or will you need to borrow money to replace the boiler? At fifty years of age there is likely asbestos that needs to be considered. Asbestos removal is ALWAYS expensive but in some cases it is only a limited amount that needs removal and the rest can be encapsulated which is much cheaper than removal.
So give us more information and maybe even some pictures of the current installation. Add in if you want to break even in five years or fifteen years. If less than five years then in most cases it will NOT be cost effective unless you have severe problems with the existing system.
To post pictures you need to first upload the pictures to a photo hosting site such as photobucket.com or villagephotos.com. and then post the public URLs for the pictures (or album) here. More pictures are always better than fewer. Please have CLEAR pictures and have both close up pictures and ones from a far enough distance that we can see how the various parts are interconnected

Yes, you will save money. A fifty year old boiler probably is operating at 50% efficiency. As Furd stated cost effectiveness is your design. Will a properly sized and installed 80%+ save you 25% - 40%? It should. Add Outdoor Reset for another 16+%. Your installed price will vary all over the board dependent on products, options and contractors.
You can get into spending a lot of money or limit the spending which is your choice. The more you spend the more fuel you'll save and the greener you will be, also the more you spend the higher the life cycle cost will be.
