NVIDIA is set to release one more nForce 680i variant that is slightly cheaper than the nForce 680i SLI. The cut-down nForce 680i will carry the nForce 680i LT SLI name and target extreme gamers. NVIDIA will manufacture the nForce 680i LT motherboards for various motherboard manufacturers.
Unlike the heat-pipe endowed nForce 680i SLI motherboards, nForce 680i LT SLI-based motherboards will have active cooling. Instead of support for DDR2-1200 memory, NVIDIA has limited the memory controller to DDR2-800.
Front-side bus speeds up to 1333 MHz remains supported. It is unknown if the nForce 680i-series will be compatible with Intel’s upcoming Conroe refresh.The nForce 680i LT SLI will continue to support NVIDIA’s SLI multi-GPU technology as well.
Other cut back features: only one Gigabit connector instead of two and eight USB 2.0 ports instead of ten. The nForce 680i LT SLI is expected in early March.
