Unless you're already about to fail, few, if any, employers will care about your GPA, and joining a large network of college graduates who share camaraderie can't hurt when it comes to finding well paying positions and moving up in organizations
"Elite" careers care a lot about GPA.
I, for one, have never put my GPA on my resume.
When a buddy of mine was interviewing at hedge funds, a few of them didn't just want his undergrad GPA, but also his high school SAT scores. He actually got shit from one of the interviewers because his French SAT scores were shady... the dude had a few years of finance experience and a PhD in theoretical physics. YMMV.
