Did you update your drivers? R9 cards require a newer catalyst driver. The one you were using for 7950 won't recognize it unless you've updated to latest versions.
Is this on windows or linux?

I've tried to update the drivers, but it says that I have the latest one installed already. When I put the disk in, it won't even let me instal drivers from it. It gives me a message saying to go to AMD.com to get the latest drivers, and there it tells me I have the newest one. The problem is that It's not even seeing the card at all. I have tried the two working cards in all 3 slots, and they all work. Even tried a different PSU just for the two cards that don't work, and still nothing. The fans run on both of the cards if that means anything.
Gonna go pick up a third card today and see what happens, but before I do, I will try what DrG said.
Your not doing it right. You can always install the driver. It's best to remove the one you have first though.
Is that gonna conflict with still being able to run my Sapphires though? I'm surprised that the computer isn't finding the new hardware when I start it up with the new card.
