Is nForce 650 the Mainstream Master?

Nvidia's nForce 600 Family For Intel Processors

As you can see on the following table, the 650i SLI is a decent product, which supports everything an educated user wants today: SLI dual graphics (eight lanes each), two available PCI Express lanes for add-ons, four SATA ports with RAID, High Definition audio, integrated Gigabit Ethernet with Nvidia's MediaShield firewall and up to eight USB 2.0 ports. The 650i Ultra basically is the same product, but it's configured for a single x16 PCI Express graphics card instead of two slots.

nForce 680i SLI remains clearly superior, as Nvidia added twin x16 PCI Express capability plus an additional 8+6 PCIe lanes. The specification claims FSB1333 system speed support, which our overclocking results clearly support. And there is support for SLI memory, allowing the system to auto-configure SLI-certified memory to run at shortest possible timings and maximum clock speeds.
