Who cares about WOW?
People who play it. Honestly, it looks fine on the default low settings. Reminds me of Quake II, but less brown and less stuffty.
Er, my laptop can handle Crysis on Very Highest at 15-20fps.
If you can call that playable you need to be slapped.
Playable is 25fps and above. Even so, 25 isn't so great, and 30 looks like stuff when you've played at 60-150 for a while.
