As I will be travelling to the US in July, I was thinking of buying two graphics cards (R9 390X) over there and bring them back to Switzerland, as computer components are mostly a bit cheaper over there.
I know that the US has some really high security standards regarding international flights. If I take these two GPU's in my carry-on luggage (so they don't break), how would a security officer at LAX react when they see those Graphics cards? I do realise that most people don't actually know what a GPU is or how it looks like. So I am concerned that a security officer might take them from me at an airport when trying to board an international flight.
Believe it or not, I read some really strange stories in forums from people that claim the security officer did not know what a GPU is and thought it might be some sort of a bomb.
Note: By "GPU" I am referring to the whole graphics card (with circuit board, coolers, etc.) and not just the processing unit.
