What kind of information do you need from the $node
object that you can't get from views standard options?
If you enable views_customfield you can add a PHP code field into the Views UI. Just add the node NID as a normal field and then add a custom PHP field, then use:
print var_export($data, TRUE);
in this new PHP code field to show you what items you can call from the views result.
One of them will be the nid so you could use node_load($data->nid);
Remember you need to add the PHP opening and closing tags around your code in the Views customfield.
You could do the same in a template or preprocess function too and if you have some complex logic that is what I would recommend.
