Towards a 4 Cores iMac?

Intel will release for Q3 2008 its first Quad Core CPU dedicated to the portable computer. The Core 2 Extreme QX9300 will be clocked at 2.53GHz and feature a 1066MHz FSB and 12MB of cache L3 in total.
The predicted TDP will be higher than the usual 20-25W, and could reach 45W. If it is for sure too much for a true notebook, it might well fit in an iMac, or in those Alienware-type of PC models.
For the iMac it will for sure remain a BTO as the price of this CPU/unit is 1038USD (public price /unit for 1000 unit order).
