Right ...
There are two issues to consider. Nothing else matters.
Issue 1 is the way the card interacts with the camera. The D70 is optimised for cards that are 40x or thereabouts. That's as fast as the camera can feed data to the card, and anything much faster than this is a waste of your money.
I use cards that 45x, and they permit me to work at the maximum speed that the camera works at; faster cards are of no use in this situation because it's the camera that is performining at its limit.
Issue 2 is the transfer rate between the card and your PC. If you use the camera cable, then you're stuck with the god-awful transfer speed that the camera is saddled with, and no matter what speed your card is rated at, making a cuop of coffee while waiting for the transfer to complete will be a good idea.
Likewise if you're using a CF reader with a USB1.1 connection. The bottleneck is your connection, and faster cards mean nothing to a slow connection.
If your CF reader is USB 2, then the access speed of your card does have real meaning, and you will see performance differences between 40x Vs 80x cards ....
Except that a 1G 40x card takes maybe 30 or 45 seconds to unload to a pc, and an 80x card might take about half that time; what can you do actually do in those extra 20 or seconds? Not a whole lot, I'd contend.
Bottom line, for a D70, is that 40-45x cards represent an ideal compromise ....
