I give it a 8/10... It would have been mice to see some Cas7 RAM & a little faster HDD (Samsung Spinpoint F3 or Seagate 7200.12). The WD Black is a great drive but the two I mentioned are faster drives.
Overclocking should be easy with your setup. I would head over to the Overclocking forum section and review some of their stickies or check out this forum, which was created by some of THG forum members for overclocking... http://www.ovaclockers.com/news.php
