Tell me the 'fx cpu horror story'.Well, perhaps the 'fx cpu horror story' is related to compatibility problems. Say, a user bought an FX CPU thinking it would work great with their new motherboard and other components. But then they found out that there were constant glitches, like the CPU not being recognized properly or causing random freezes in the system. This can be a real nightmare for someone who has spent a lot of money on building a PC.
