does having 2 cards use up the bus twice as quick?

 

Each card has its own bus, and they can also communicate (synchronization, and I believe some types of resources are shared) without going the long way around through the PCI-E bus, to system memory, back to the PCI-E bus of the other card, as they can just use the SLI bridge.
