AnandTech: nForce4 SLI Roundup: Painful and Rewarding. _Well the results are in, basically, if you are happy with 8xAGP (and there is no difference in real performance right now between that and PCI Express), then use a "nForce 3":http://www.anandtech.com/mb/showdoc.aspx?i=2128&p=19 boards like the MSI K8N Neo2, so get one of the two board below if you have to have SLI and are willing to spend $800 for graphic cards (!!!) or like PCI Express_
The DFI nF4 SLI-DR is the board of choice for overclockers who wish to squeeze every last bit of performance from an Athlon 64 SLI system. The range of overclocking options and the overclocked performance are the best that we have seen. While the feature set is more or less average for SLI-class boards, the design and performance of the Karajan audio module particularly stands out as an example of the creativity that went into this board's design.
The MSI K8N Neo4/SLI Platinum has the best combination of robust operation at stock speeds, top-notch overclocking abilities, and the best feature set and feature performance of the available SLI boards. Buyers looking for the best feature set that truly enhances system performance will choose the MSI. The 2nd SATA2 controller, dual PCIe LAN, and hardware SoundBlaster Live! 24-bit are a standout combination in a crowded field of top-performing motherboards.
