MSI leads the rest in introducing one of the top notch P4 mainboard supporting the new series of 533Mhz FSB P4 CPUs. Indeed, there is not much of a technology difference between the i845 DDR chipset and the i845E chipset ; the latter supporting the official 533Mhz CPUs. Something that makes a difference is the capabilities of this board. It has an amazing line up of features that you would never have thought of. One such capability is the Bluetooth PC2PC which I am pretty impressed. Kudos to the hardworking and innovative MSI engineers which makes this possible - a first in PC history, a PC with built-in wireless connectivity.
