“The 680i SLI motherboards were launched with a tremendous public relations effort by NVIDIA back in November. There was a lot of hype, speculation, and fanfare surrounding NVIDIA’s latest chipset for the Intel market, and it promised an incredible array of features and impressive performance for the enthusiast. At the time of launch we were promised the mid to low range 650i SLI and Ultra chipsets would be shipping shortly to flesh out NVIDIA’s Intel portfolio. NVIDIA had plans to truly compete against Intel, VIA, ATI, and SIS in the majority of Intel market sectors within a very short period of time after having some limited success earlier in 2006 with the C19A chipset.
However, all of this planning seemed to unravel as the weeks progressed after the 680i launch. It seemed as if NVIDIA’s resources were concentrated on fixing issues with the 680i chipset instead of forging ahead with their new product plans. Over the course of the past few months we finally saw the 650i SLI launched in a very reserved manner, followed by the 680i LT launch that offered a cost reduced alternative to the 680i chipset. While these releases offered additional choices in the mid to upper range performance sectors, we still did not know how well or even if NVIDIA would compete in the budget sector…”
