No, go with what you've got. If we sieved all the bits out of our garden the whole thing would sink by several feet.
A lot depends on what you want to achieve but something desirable will grow in whatever you have. You can always enrich pockets for anything that can't cope. I'm a great believer in planting to suit what you have rather than struggling to grow what doesn't want to grow
