SAT composite vs. individual sections

Do colleges look more at the SAT composite score, or the individual parts of the SAT? I got an 800 on the math, 620 on CR, and 640 on Writing. If I retake the SAT and let’s say that I get a 700 on CR and writing, and my Math drops to a 730. Will colleges pay the most attention to my highest scores from the different times I took it or my composites?
