Need to know how much SAT writing matters in college admissions.

I got a 2220 SAT and while I am happy with it i know i could of done better on the writing portion. I got a cr:770 math:780 :
writing:670. My math and critical reading scores are great, but my writing score brings it all down. How much will colleges care about the writing?

Some colleges don’t look at the writing score at all and generally they care less about writing than CR and Math.
