NVIDIA'S NFORCE4 SLI chipset has been out for about a year now, so it's due for a refresh. That refresh comes in the form of the nForce4 SLI X16, a new chipset that addresses one of the main criticisms of the original nForce4 SLI: the fact that it only provides eight lanes of PCI Express to each graphics card in SLI. The new SLI X16 chipset provides—you guessed it—16 lanes of PCI Express to each graphics card in SLI, with enough lanes to spare for additional PCI-E slots and peripherals. Support for RAID 5 has also been added to the nForce4 SLI chipset for the new X16 edition, bringing NVIDIA's K8 platform up to feature parity with its Intel Edition chipset.

Asus' A8N32-SLI Deluxe is the first nForce4 SLI X16-based Athlon 64 motherboard to hit the market, and it's more than just a simple refresh of Asus' nForce4 SLI design. The A8N32-SLI is equipped with a swanky new heat pipe cooler that keeps its VRMs and chipset cool without making a sound. It's also loaded with extra peripherals and eight-phase power. Oh, and it overclocks like mad, too. Read on for more on NVIDIA's nForce4 SLI X16 chipset and Asus' excellent implementation in the A8N32-SLI Deluxe.
