What's your time frame? Age? Do you need accessibility and liquidity? Are income taxes an issue? How is the rest of your portfolio positioned? Do you have a specific need for the money in the future and if so, when?
These are some typical questions I would ask if someone walked into my office with $80K and asked what to do with it. The answers to these and probably more questions would determine the best place to invest the money.
