We test Asus' smallest board capable of carrying a 6-core CPU.

Asus challenged us to test the fact that its P6TD Deluxe can overclock a Core i7-920 D0 to 4GHz - and run it overclocked, all day, everyday. We put its claims to the test, and show you BIOS settings so you can get the same results at home.

Our first (of many) P55 motherboard reviews starts, as ever, with Asus' Deluxe. It's expensive and bridges an awkward middle ground between Republic of Gamers and lesser featured boards, but does it still command excellent Asus quality and must have features that makes it a must buy?

With DDR3 prices dropping faster than the FTSE, AMD's AM3 motherboards, like the Asus M4A79-T Deluxe, are becoming really quite attractive. Built on familiar M3A79-T technology - one of our favourite AM2+ boards - does the latest generation offer an equally great buy?

While we've been inundated with P45 boards from across the breadth of the motherboard world, Asus is the first to us with a BIOS that works well. We take it for a full spin to see if Intel's highly anticipated new mainstream chipset is a worthy successor to the massively popular P35.
