I have a CS degree and pursued a marketing MBA. To make it short: i) a great product with basic marketing trumps a bad product with "fantastic marketing" on the long ii) the product makes the money, not the marketing iii) one can't hold both a CS and a marketing role at the same time as business grows, you will have to choose one or the other.
