Hexus.net has a review of the Gigabyte GA-K8NXP-SLI that can be found here.
“The GA-K8NXP-SLI oozes of being an enthusiast’s motherboard, and it shows throughout, from the thoughtful packaging which doubles
as a test bed for the board through to the comprehensive set of overclocking features available in the BIOS. Performance is also
generally on a par with other nForce4 boards we’ve seen, and the whole system was rock-solid stable throughout. The appearance of
Gigabyte initiatives such as DPS and Dual BIOS add to that feeling of powerful stability, even in a worst case scenario such as a BIOS
failure or power surge.”
