FWIW, the manual says that you need to use a card with a read/write speed of 8 MB/s.
Anything faster will make downloading to your computer quicker (if you have a FireWire card reader or ExpressCard reader) and might give you an advantage when shooting stills in burst mode. But it won't change anything when recording video.
So called 133x cards say they will give you 20MB/s write... so that's WAY more than you need for video on 7D.
