Depending on your point of view, the NV 3DS SLI requirement is either boon or bust. Some people view it as a limiting factor as it requires two cards and an SLI motherboard. Others view it positively as the SLI requirement ensures you have significant horsepower.
As of now, NVIDIA hasn't released a "GX2" board since the GTX295 - completely bypassing the GTX400 series. While we await news of a GTX in the GTX500 series, EVGA is releasing the GeForce GTX460 2Win. EVGA shows performance gains over the GTX580, with the expectations of lower power, heat and noise.
