Not sure m8, the last time i played with SLI was about 2-3 years ago

There is a little here http://www.slizone.com/object/sli_cuda_learn.html about different solutions though.








I did find this though, nothing to do with SLI, but its scans drivers currently installed and offers a pre-release version for you.
