I want to purchase a Asus Maximus Extreme Motherboard. Which Extreme Motherboard is the best from $300-$360 range to allow me to overclock the best? I also need Ram. Or do I want a different Asus motherboard. I prefer to stay with an Asus Brand.
The Motherboard and Ram need to be compatible with the Noctua NH-D14 cooler. http://www.noctua.at/main.php?show [...] A1155_Asus
Thanks The noob.

It troubles me that there are so many types of motherboards for the 1155 chip, Asus has the H61, H67, P67, Q67, C206, and Z68, what are these different north or southbridge Chips on the motherboard? I'm confused.

Triple Channel Memory Kits are packaged for Intel X58 chipset (i.e. triple channel) motherboards.

You should be looking for 1.5 Volt or lower Dual Channel Kits or a Quad Channel Kit.
