They've also added support for the Asus Turbo Key, an easy way to change processor clockspeed and voltage. The company has at least eight M4 models in the works, all based on either an AMD or Nvidia chipset. At the high end they have the M4N82 Deluxe, with the nForce 980a SLI chipset. At the lower end they have three boards available with integrated video, including a GeForce 8300, a Radeon HD 3200 and a Radeon HD 3300.
There aren't many AM3 boards available now, especially not high-performance boards. With more of these available, we'll be able to see firsthand how the Phenom II performs in real-world use.
