I've never gotten a card with it on it; I've always had to flash it.
Flashing these cards is a bit of a highwire act and can brick them, but
I've never had it happen myself. With that said my real reason to flash
all of mine is to have all of them on the same firmware just so I can
eliminate that as a possible contributor to problems if one starts
acting up and the others are not. It's more of a "good practice" thing
than a need IMHO; it's not a lot of fun to try to run down a problem
only to find out after much hair has been pulled out of one's own head
that the problem is bad firmware on a board!
