Because of FSB issues surrounding the nForce 5 series for Intel, Nvidia have gone back and revised the boards. I’m not entirely sure what’s changed here, perhaps someone can comment on this and tell me whats going on?

NVIDIA’s new nForce 650i SLI and 680i SLI aren’t exactly new per se but rather a quasi-re-branding of the previously released nForce 570 SLI and 590 SLI Intel Editions. The new nForce 650i SLI SPP pairs with an nForce 430 SLI MCP to provide a total of 29 PCI Express lanes. In SLI mode the nForce 650i SLI delivers two half-speed PCI Express x16 slots.

NVIDIA’s nForce 680i SLI is essentially a revised nForce 590 SLI Intel Edition. Manufacturers were reluctant to adopt the nForce 590 SLI Intel Edition due to front-side bus scaling issues. Nevertheless the C55 nForce 680i SLI is paired with the nForce 590 SLI MCP a total of 48 PCI Express lanes. As with the nForce 590 SLI Intel Edition, the nForce 680i SLI supports two full-speed PCI Express x16 slots. The C55 are essentially C19 chips with updated memory controllers.
