I don't know what this is all about but you cannot replace the video card on an iMac because it is built into the logic board.
In fact I am in the process of replacing the logic board on my old iMac G5 because of a bad GPU. I managed to find a used one with a warranty.
Maybe that's what the repair shop did. $300 sounds about right on price. If Apple replaced it it would be much more.
