The minimum GPA one needs is a 2.0. Anything below that and you will be kicked out of the university.
If you can get a good GPA do it. Not all but many internships will ask about it. If you ever want to go further (masters, mba, etc) you will need a 3.0+
I never cared about mine and don't really know what I graduated with. I think around a 2.5. Now that I've been working for a few years it definitely doesn't matter but I do always think it would be nice to go back and get a mba or something.
