This does not look like possible, but I want to know that kind of system actually need to run a 6 way SLi gpu setup. I had seen maximum of 4way sli. Is there any motherboard which comes with 6 gpu slots. That would be an awesome machine and surely the game performance would be unbelievable. I cannot figure out why they are not making 4 way sli more common and cheaper to the users. The thing that mostly matters is configuration. It is far more complicated for use like me to run 3 way sli properly on existing board.
