In our recent review of the MSI K8N SLI, we took a look at a no-frills nForce4 SLI board made for a lower price bracket. This time around, we take on a feature-packed enthusiast level nForce4 SLI motherboard that is also selling at a lower price bracket. That's right, we didn't make a mistake, the ECS KN1 SLI Extreme comes with the typical features found in all high-end power user boards, but sports a mainstream pricing that ECS has always been able to leverage upon.

The ECS KN1 SLI Extreme is basically the big brother to the nForce4 Ultra based KN1 Extreme. However, this isn't just a chipset update to a PCB template scenario, ECS has actually made use of the time between these two product launches to make multiple improvements to the KN1 SLI Extreme. Whether these improvements will make it a better board or not is to be seen, so let's get on with our review without further ado.
