I would max out my contributions to a 401K only up until the company match, then switch to a Roth IRA, where I would max that out (~$6K for most people), and then switch back to the 401K or whatever investment vehicles you want.
Here is a helpful webpage that outlines why this is the best strategy:
IRAs and 401(k)s have similar tax benefits but key differences. See the pros and cons in the IRA vs. 401(k) decision, and how to pick what's best for you.

Roth IRAs have incredible advantages over a traditional 401K for the vast majority of Americans. It's a crying shame that more people are not using them.
