Why not? Embarrassingly-parallel problems (of the kind you'd use a GPU for) are a perfect use-case for enhancing fault-tolerance through redundancy (i.e. running your program on three cards at once and only accepting the output if they all agree.) The only place this doesn't apply is gaming, where you're trying to get realtime interactive results while economizing on both cost and energy. But for every other use of a GPU, you can't go wrong with "throwing more compute at the problem."
