So you're saying that for 20 more dollars you can step up to a GTX 680? If that were me I'd jump on it, even if I'm trading a lifetime warranty for a three year. In three years you'll probably be upgrading the card anyway (Well, I don't know about you. I probably would be). The 680 runs cooler, uses less power and increases performance substantially. If it were me, I would be all over it. Just my 2 cents.
