ABIT KN9-SLI Nforce 570 SLI Mainboard Review

Intel is getting all the limelight nowadays with their upcoming Core 2 Duo, but it’s fine time we shifted our attention back to AMD and the Socket AM2 Motherboards. Introducing the Abit KN9-SLI, based on the NVIDIA nForce 570 SLI chipset!!

AMD has been rather overshadowed by Intel as of late due to the launch of the Conroe and Allendale processors, but with the introduction of the AM2 socket and the proven overclockability of the Windsor core, we should not be neglecting this platform at all. The Abit KN9-SLI is a mainboard based on the Nforce 570 SLI chipset that’s tailored for the Mid-range budget gamer. It features a single chipset solution that enables SLI with 2 x8 slots. The KN9 SLI comes in a bright orange package as many of their previous boards do, and like many other manufacturers, Abit has adopted a heatpipe cooling system for their Nforce bsaed mainboards.
