Perhaps in an effort to keep costs down, ASUS opted against equipping the board with NVIDIA NF200 bridge chips and a four-way SLI license. The decision makes sense, as very few users are ever going to utilise a four-way GPU configuration, and both the added expense and additional power draw (each NF200 chip eats up around 6W) are essentially drawbacks for 99 per cent of users."
