You are attaching via USB either way...unless there is a USB version difference between your camera's cable and your card reader's cable (or the port you are plugging into), I don't see how there could be any real difference other than the fact that you are dealing with larger files which can certainly happen as you upgrade to a new body.  

The difference could be the new software (no choice here) processes the image more slowly as that is the other change made at the same time. I would think the build in reader would be faster than the USB but maybe not. At any rate it is what it is. 

Thanks for that. I've been away for a bit so a bit slow here. I have been using my built in card reader in the computer. I realized after a bit the files are likely 50% bigger but it is easily twice as slow even using the reader as opposed to cable as I always did before. I just have to leave it churn away when there's a lot I guess. I look into the photo mechanic. Thanks again.
