www.semiwiki.com has over 5000+ CMS Articles. They won't be there long though the owner has tasked me with converting everything vBulletin the CMS and Forums to Wordpress which is happening very soon I even had to customize an older script to import the CMS Articles.

vB4 CMS works fine as-is but its not as easy and simple as Wordpress nor will it ever be (as vB4 CMS is not being improved since vB5 is out etc etc). I've seen many sites that utilize vBulletin as the forum with a bridge or SSO (single sign-on) where it worked great and the site owner had an easier back-end to use for their front page (WP ).

Edit: Some things are useful though from the vB CMS, such as promoting a forum thread to an article, which by using Wordpress you would not be able to do unless you did that manually - is that one feature solely a good reason to use it over another software such as Wordpress, well no not to me but to some it might be. I would install Wordpress in a sub-folder on your site and give it a spin, it literally takes less than five minutes to install and then you can see how creating a new article (post) compares in Wordpress to that of your vBulletin CMS and make a well-informed decision then as to which one feels and fits better for you!
