NVIDIA has, as we have told you so many times before, chosen to more or less trash nForce 590 for the Intel platform, since the circuit has proven to be a far from an optimal enthusiast circuits. Instead it will now launch nForce 600 through 680 SLI, 650 SLI and 650 Ultra. The new circuit will be capable of 1333MHz FSB, if this is overclocked or actual support for the next generation of Core 2 Duo we don’t know for sure. NVIDIA says that it will be possible to clock it even higher though. It has also increased the number of PCI-E x16 slots to three, where the third is for NVIDIA’s physics solution, which most likely will use Havok’s software.
The difference between 680 and 650 is the extra PCI-E x16 slot, while the difference between SLI and Ultra is the same as always. NVIDIA has also updated the memory controller to make it possible to run memories, via dividers, up to DDR2-1200, but also support for EPP. More about nForce 600 can be found at DailyTech.
