Nvidia rolls out nForce 590 SLI chipset

Santa Clara (CA) - In a day of dueling chipset announcements, Nvidia has rolled out its new nForce 590 SLI MCP chipset. The chipset comes with built-in QoS for gaming traffic and Nvidia's "LinkBoost" which increases PCIe bus speeds with certain video cards. Dual Gigabit Ethernet ports and a RAID 5 SATA controller are also integrated.

As the name suggests, the 590 SLI can handle multiple Nvidia graphics processors. Up to four chips are supported in quad-SLI mode. In addition, the board has features that should appeal to avid gamers: Overclocking is supported through enthusiast BIOS templates and Nvidia's nTune software utility. Gamers may also like "FirstPacket," which prioritizes gaming traffic and promises to reduce lag.

Owners of the latest Nvidia graphics cards will be able to take advantage of "LinkBoost," which increases the bus speeds of the PCIe bus. Motherboard makers like Gigabyte are claiming that you will get up to 25% faster clock speeds when you pop in a LinkBoost-enabled GPU like the GeForce 7900 GTX.

Up to six SATA hard drives can be attached on the chipset's single controller. Nvidia claims that it is the first controller that can support two RAID 5 arrays.
