According
to Beyond3D, NVIDIA is now silently introducing the nForce 650i Ultra, and
it should be available shortly. The motherboard will use the same chips as the
nForce 650i SLI (C55+MCP51, while the 680i Series uses C55+MCP55) but will be
substantially cheaper while the physical layout will only sport one x16 PCI-E
slot, compared to the 650i SLI which had two and was capable of running in 2x8
SLI mode. The nTune release notes for version 5.05.25.00 confirm the product's
existence, and when they asked NVIDIA directly, they told them it will be
available for roughly ~£50, so you should expect products to be available in the
70-80 price range most likely. This is a fairly significant price cut compared
to the 650i SLI, since that seems to retail for about 100 to 120.
