There is no single correct answer to that.
It depends on many variables, such as the size of the dataset, the load your
site is under, the amount of RAM in your server, how much bandwidth you
have, how often the selectedindex gets changed, how fast your servers are,
etc.
The only way to be sure would be to do some load testing against both
designs.
In general caching is a good thing, just don't go overboard with it.
