Speed:

recent DSLRs have pretty big buffers now, so the speed of the card is less important than it used to be; also all the cards are faster now

I don't think a DSLR will have a problem unless you are shooting video, Grady.

I am not so sure about a Point & Shoot type cameras - I have a couple of those and have not had any problems -- my speed is usually limited on those by the lack of an optical viewfinder, shutter delay & handling issues.

What 8 M camera are you using?

I don't think the speed to the computer is too critical.
