NVIDIA will soon launch its nForce 570 LT SLI chipset:
The new silicon, which will be placed right under the 570 SLI will feature support for AM2 CPUs and will boast 19 PCI-Express lanes that enable x16 + x8 SLI configurations and will also work with dual x8 setups. The nForce 570 LT SLI will come with 4x SATA, 2x PATA ports and one Gigabit Ethernet card. The new chipset will lack EPP (Enhanced Performance Profiles) support.
The first motherboards with the nForce 570 LT SLI should arrive later this quarter.
