It looks like NVIDIA is working on two budget chipsets, the 650i SLI and 650i Ultra:
According to a DailyTech report, the 650i parts are identical in all but one regard: the SLI version supports a pair of x8 PCI Express graphics connectors - most likely implemented as x16 slots - while the Ultra model can host just one graphics card.
Both chipsets have four 3Gbps SATA ports, though they will support drives in RAID 0, 1, 0+1 and 5 configurations. Gigabit Ethernet is part of the package, along with Nvidia's FirstPacket quality-of-service system.
