You can no longer mod the DFI LanParty Ultra-D to perform SLI. The DFI company has discovered this and has made all future Ultra-D main boards unmoddable to SLI. If you want to go SLI in the future, there is no way that you can buy a non-SLI board. They have also prevented this buy not supplying an SLI - bridge essential for SLI. *NOTE* The SLI bridge does not come with the video card- it comes with the motherboard.
