While a lot of the focus on computer motherboards has legitimately been on the X58 chipset and the Core i7 CPUs due to the increased performance and new features of the combination, there is still a market for P45 based motherboards and Core 2 CPUs. After all, the platform cost for a X58+Core i7+ DDR3 memory is far less than buying a P45 based motherboard+ Core 2 CPU+ DDR2 memory. With the economy the way it is value is becoming more and more important.
