I'm heading to the Apple Store tomorrow and they have both the Quad Core and Duo Core in the 27 in model now. I'm a student...not a video editor, gamer, or musician, so using it for those purposes would be completely foreign. I'm purchasing it specifically for web and iWork use. It would be nice to save hundreds of dollars, negate the fact that I can afford the Quad; however, one of my friends made a good point. Future Proofing the iMac! Meaning to get the Quad core since it is now available and not having to worry about getting a Quad later when every other iMac will come standard with it. This will be my second mac...but I would still like to know...Does Quad matter when using it for regular web base surfing? Or should I settle for the duo? I need some advice and facts...I'm still pretty new to Mac.
