XFX 680i LT SLI Motherboard

Nvidia also only released one chipset in its nForce 500 series for Intel, however, since it was based on the older, poorly overclocking nForce 4 SPP northbridge, Nvidia quickly dumped 500 series for Intel, which gave birth to nForce 600i series chipsets. Today there are four chipsets in the 600i series, 680i SLI, 680i LT SLI, 650i SLI and 650i Ultra in order from high-end to value.
