so, the cards are not in a running computer ,correct .
without numbers on them and not installed in a working computer it gonna be hard to identify them .
my experience with video cards is that there are numbers on all of them somewhere ??
any chance of posting picture of the cards , both sides of the card for us to see.
also ,if you install them in a working computer it likely windows will have drivers for them ,to function ,if the old P4's are worth keeping its also likely that the 4 cards will be fine too
