A loop outside the normal loop

<!-- loop name -->
<?php $myloop = new WP_Query('category_name=CATEGORY&showposts=3');

<!-- Posts in my loop but skipping the posts (IDs) in the array loop above
<?php while (have_posts()) : the_post(); ?>
<?php if (in_array($post->ID, $myloopIDs)) continue; update_post_caches($posts); ?>
