NVIDIA have officially launched their new nForce 680i SLI LT chipset today, this sits in between the 650i SLI and flagship 680i SLI models. The noteable differences between it and its bigger 680i SLI brother are the lack of a 3rd (x8) PCI-e slot, only one gigabit ethernet port, inferior chipset cooling, LinkBoost and less BIOS options for tweaking. Those things aside, it's very much the same as a regular 680i.
With the NDA lifted on on this new chipset, theres quite a bit of coverage surfacing as per the links below (which i'll continue to update over the next 24 hrs) :-
Today, Nvidia is looking to fill the gap between the 650i SLI and 680i SLI with a new product, the nForce 680i LT SLI. This chipset, which is a trimmed down version of the full-blown 680i SLI, is targeting the $199 price range "sweet spot" to compete against the Intel 975X chipset. This move allows Nvidia to counter Intel's offerings at every major price point. The first board hitting the market will be from eVGA, but it was designed by Nvidia themselves. We've managed to get our hands on a board for an evaluation and will showcase it here for you today.
