The death..

That won't do anything to the video card, even if you place those magnets on top of it while it's turned on (unless the magnet is made of a conductive material and you short the board with it. But that is pretty much the same effect of any conductor material and has nothing to do with the field per se).

Only hardware affected by standard static magnets are the hard disks, flash drives, floppy disks, CRT, and all hardware that relies on magnetic media or metallic magnetic foils, such as a CRT tube).

Commercial magnets are nowhere near powerful enough to damage a circuit board. Variable fields might cause inductive effects, and powerful industrial magnets too. But you have never seen any of those. They are on factories, not in consumer electronics.

Using a magnet long enough will screw up your screen.. If its only a bit of time, the chances are slim it will leave a 'stain' on the monitor. But usually these kinds can be fixed by Degaussing.

But in terms of Vid Cards, Korrd would be correct on this..
