EVGA 680i LT SLI: NVIDIA's 680i Cost Reduced
 

The real differences between the chipsets are the missing features on the LT chipset. These include the loss of two USB ports (10 down to 8) and a Gigabit Ethernet port. The DualNet teaming feature is no longer available but will probably not be missed by the vast majority of users, nor will the loss of the second Ethernet port. However, the loss of two USB ports could cause issues with users who have several USB based peripherals. One of the last options to go is the third physical PCI Express x16 slot that operated at x8 speeds electrically.
