For those who have owned or have had a great deal of experience playing or watching WoW on a 2010 model MBP (the lowest one on the current referb totem pole, with 256mb 330m graphics) how does the game run? Does it keep a consistent fps with decent settings? Does it hold up while raiding? For a point of comparison, we are deciding between the $1200 referb pro and the $1100 referb iMac (which has a 512 card in it), and the lady greatly prefers a second laptop over the iMac so long as the laptop is a good price and does WoW right. Thanks!
