Your fastest card will only write as fast as the slowest card. In other words, you will not achieve 1000x speeds since I don't think there is a 1000x SD card. It's an annoyance we 5D Mark III owners are hoping will be fixed with a future firmware update.
As you can see from the RG database the 5D3 is crippled in write speeds when you use SD cards. It does not utilise the lates faster SD so you will only ever get Just under 20mbps . And I think you reduce the cf channel to that speed also .
Also if you shoot raw to the cf and jpeg(any size) to the SD your buffer is 6 shots .
Interestingly the buffer of the 7D was reduced to 6 when shooting dual format. Now with the new irmaware it's increased to 18 .
