> I have a few friends who did this. They were barely able to get WoW to run at the lowest settings on their MacBooks.

Were they just doing that as a test? Because there's a Mac version of WoW...

MacBook Pros have substantially better GPUs than straight MacBooks.

I still use a Macbook Pro from 2007 that I play games on via Bootcamp. It's only recently starting to show it's age when I play new games.
