MSI has showcased its upcoming P45 motherboards and the top notch one has three PCIe 2.0 slots. This is the main difference compared to the P35 chipset generation and, naturally, there is some additional optimization to make this board more attractive.
The board supports all new 45nm CPUs and, of course, the old 65nm will work. It comes with Hi C capacitors on PWM. It has one PCI slot and two PCIe 1X, and it supports DDR3 memory.
If you still like DDR2 there will be a P45 Platinum, and if you want two PCIe slots and DDR3 memory you can simply go for P45D3 Platinum; and these two will have two PCI slots if you still need them.
