Interesting. My current Alienware m7700 (256 mb video card, 3.2 ghz P4, 3 GB of ram) can run WoW on slightly downgraded graphics (ground graphics density and shadows downgraded) without much issue, but does get a little choppy in highly populated areas.
I guess I can expect my new MacBook Pro (2.93 ghz Core 2 duo, 4 GB of ram) which is currently being shipped to run WoW on full blast without any issues at all eh?
Awesome!
