Will using Entity Framework be a good choice for databases containing tables with 80k-100k records?

I am working with VS 2010, Entity framework, SQl-Server 2005, ASP.Net web forms. Currently, I am working on the Data access layer library which soon will be a web service, using Entity Framework collaboration with different design patterns like repository pattern and some best practices that posts in different blogs. I am also test each repository using the Unit testing project. Thumbs up! Working fine.

The thing I am worried about is, will I benefit from using Entity Framework when retrieving data from tables containing 80-100k recor开发者_如何学Cds?

Thanks

I go with @SteveCav and @Craig Stuntz comment. I just tried with a table that has more than hundredth of thousands records. It just works fine.
