^ I have only recently heard of it, It frankly sounds like a really bad idea, I have never tried it,I might as I have an old dead HD6870, but I really do not see how it would work. it claims to re flow the solder or something, but the plastic might melt before the solder does. and I really am unsure of what softened solder would do, it would only help with a PCB crack not a dead graphics core. if the card seems like toast, you can treat it like a piece of toast and toast it, but only on a card you really would not care if it is dead. (a dead card) I need to research this idea, I have been asked about it quite a lot lately.
