Ive just started to play Wow on it today, had a 10 day trial a couple months back.
Runs very well! Everything high with 2xAA and 4xAF, only need 2xAA on my MBP as the res of the sceen is sooo good! 1650x1050
This is on a MBP, 2.33, 2gb, 256 X1600
You'll need the pro just for the quality graphics chip.
