I vote 4 or 5.
I also vote 4 or 5. White space = better. Excess boxes = not better.
Excellent. I was leaning towards 4.
I would vote for 1, but remove the box around your name, and just have the single solid line. It kind of looks like a balloon or lollipop right now. But, too much white space is boring.
Also.. the word "work" in there is odd. Either change it to "work history" or "experience" or something else.
