While the physics card is really quite useless, the company also makes video cards, which ARE very important. And video cards from BFG, eVGA, and XFX have lifetime warranties.
XFX calls theirs 'double lifetime' - lifetime for you, and if you sell the card, the second hand buyer gets a lifetime warranty, too. eVGA and BFG also tend to 'upgrade' you if you have a much older part that dies (IE., if the card you have is out of production and they cannot replace it with the same model, they replace it with a similar model of the current gen).
