If one thing is certain about the motherboard chipset market today, NVIDIA controls the high-end of the Athlon 64 market with their SLI platform. VIA, who used to own the market with the KT890 chipset, is all but out of the market for the hardware enthusiast. SIS is a name that used to dominate the Athlon market along with VIA, but today are barely a blip in the radar for the enthusiast. ATI has good chipsets with their Xpress 200 and CrossFire boards, but just don't have the product for multi-GPU solutions out for purchase in quantity. EVGA is one of the big names in NVIDIA partners for their video cards. Recently, EVGA has also branched into motherboard chipsets as well, with the nForce3 250GB being their first motherboard chipset. EVGA recently announced their version of the nForce4 chipset, the NF43-AX. Today, I'm reviewing the EVGA nForce4 SLI Edition motherboard, the EVGA 133-K-NF41-AX.
