ECS has done a wonderful job with this motherboard. Feature-wise the ECS KN1-SLI Extreme scores above 40 points on our scoring system with extra points for SLI support. ATI has finally released their answer to SLI, Crossfire and their next generation x1xxx series of video cards, but NVIDIA has lowered the MSRP of SLI to mainstream prices, making it even more attractive to the gamer crowd. Performance of the board is typical of SLI motherboards thus far tested on the site and therefore placed somewhere in the middle, which is not a bad place to be at all considering the performance differences are minimal in any case between the fastest and slowest.
SLI used to be limited to the same model cards and require a SLI bridge. Today, with the release of the 81.84 beta drivers on Nzone.com, NVIDIA's SLI works without the Golden Finger Bridge and you can mix different cards and clock frequencies. I tested SLI with 2 EVGA 7800GT COs and it worked without issue. NVIDIA has announced the successor to SLI, the 32-lane SLI boards. Current boards provides up to two 8x PCI Express lanes working together to improve performance when using two video cards. Boards like the ASUS A8N32-SLI have two x16 lanes in operation at the same time when in SLI mode. We'll have to wait and see if it makes a significant difference, but it sure sounds good on paper. AMD for the first time beat Intel at the sales counter last month, and shows the winds of change blowing in an NVIDIA AMD favoritism that shows Intel's tight reign waning as the world spins into the new century.
