I now have a EVGA 9800 GTX+ and would like to SLI another but cant find any quite like mine anywhere except tiger direct where it is unavailable. My 9800 GTX+ has 2 6-pin power connectors where all other evga GTX+'s only have 1 6-pin connector. My question is, does it matter if the two cards you SLI have different connectors. I would also like to know if there is a reason the double 6-pin is rarely seen.
