my main point was if you are looking to buy a new computer. if you have a quad core than it would not be worth the money to upgrade. so i agree with you. but if you are looking to upgrade to a quad core than don't, go with the i7. they are both about the same price except for the cost of memory.

wow is not a very difficult game for a computer to run. i played it on my 3.5 year old g4 mac mini just fine. playing on my g5 macbook was not much of an improvement. mostly if your harddrive is fast enough and you have sufficient memory, almost any intel 2 core will be able to multibox wow.

once you meet the recommended system requirements everything over that is over kill. running 5 wow's really means you need more ram and faster hard drives. not the fastest cpu on the market. but if you thinking about buying the quad than get the i7.
