If you plan on playing wow at all you will have to have it set everything to the lowest.
When I use my laptop to play wow I have to play lowest everything sept for view distance and spell detail. *otherwise i couldnt raid*
You also happen to have about half the score in 3dmark05 that I do. *well your card generally does*

I get about 15-30fps in 25 mans.
In 10 mans I get around 25-45.

So don't expect much with your card.
