MSI made a brief introduction of its upcoming X38 based motherboard. This might be among the first board to support Intel X38 high end chipset. This Ultra high end motherboard will be really overclockable and it comes with 4 Phase PWM design.
The most interesting is the four PCIe express physical 16X ports all PCI 2.0 ready but electronically two of them are PCIe 16 while two are PCI 4X. This will still be enough to host four PCIe cards at the same time.
It also comes with 4 DDR3 memory slots and 2 DDR2 slots so it will make the transition really easy and the board comes with well known X-Fi audio.
The board should be ready in September time.
