Graphics life in general a few years?
At present, the mainstream graphics are three-year warranty, some manufacturers may wish the life of the game graphics settings is generally about 3 to 5 years. 
To a day's work 8 hours a week, 5 days per boot, in theory, can be used on the graphics card three to five years, or even longer, not bad. In particular, some high-end alone significantly, due to the workmanship and materials abundant life may be longer, more durable, and some even with 10 years are not bad, it is there.
However, note that these are mostly high-end graphics cards, because working with the material itself is different, so their durability will be higher. Secondly, different working environment is going to affect the life of the graphics card, such as CPU overclocking long-term, stable power supply, chassis-card cooling environment, dust, and the use of time will have an impact on the life of the graphics card.
Therefore, the service life of the graphics card is not an accurate number, I can only say that the general mainstream video cards, can be used normally about 3 months to 5 years. However, due to various reasons itself, external causes, they are also cards with a bad two years, but some spent more than five years, or even six or seven years did not bad.
Long-term full load operation or how long life mining graphics in general?
For a long time or full load operation of mining graphics, because in the long run at full capacity, the graphics card has been in operation at high temperatures, will greatly shorten the life of the graphics card, basically 2012 will be a problem, a good physique point graphics, life is relatively long a little. But in this state long-term, and long life will not last long.
In view repair sister, mainstream graphics cards, there are roughly 3-year warranty, so the normal use of a 3 to 5 years without much problem, of course, if you take the card improperly man, he accidentally bite the tongue suicide. . . . .
The last repair sister suggested that they could not take the card when the "people" look, but give it a cool environment or must regularly clean up the dust, and regular monitoring about the whole thing, there is not a long time so they are in a full state, or is burn card. . . .
