There is no "best" build for, anything really. There's just what you feel good using. Test run a few cookie cutter builds and see how they feel, and stick with the one you like best.
Edit: Forgot to mention the little thing called the sticky at the top of the page. Check out the talents section for a nice rundown of everything, and a link to a nice dps build.
