I haven't purchased the card yet. I keep shuffling possibilities. What about using the TITAN as main graphics card and the GTX670 for PhisX setting it in Nvidia Control panel using a SLI? I read that is no longer required to use the same GPUs to make that. It's that a possibility? Will I get better performance than just the TITAN alone?
Right now, the second GTX670 wins the TITAN for 70% vs 30%. If its possible the SLI I will seriously reconsider the possibility of changing my mind.
