780i SLI vs 750i SLI -is there a noticable difference?

Okay, lets say I am getting two 9600GTs to run in SLI. So now to choose my motherboard. The chipsets I am deciding over is 780i SLI and 750i SLI. Is the SLI performance that drastic between the two?

well I mean apparently the PCI-e bandwidth is smaller on the 750i SLI compared to the 780i SLI when doing SLI, so will that effect my performance?
