While I've been concentrating on AMD chipsets for their new Phenom II CPUs, there is another chipset manufacturer that manufactures chipsets for their CPUs, NVIDIA. NVIDIA makes chipsets for video cards, motherboards, and handheld devices. Their latest chipset for the AMD platform is the NVIDIA nForce 750a chipset which is the basis for the M4N72-E motherboard I'm reviewing today.
ASUS motherboards tend to be best of the best in terms of performance, features, overclocking room and more. The general trend of the computer industry is that there are Tier-1 motherboard manufacturers like ASUS then there are lesser known manufacturers like ASRock who are a subsidiary of ASUS to make the mainstream versions of the boards ASUS makes.
