Is it harmful to a GPU to push it to its limits for hours at a time?

Also I've heard that the cost of electricity can make mining unprofitable if you don't get a good hash rate (I have an Nvidia card so I get about 15 hash/s), but I usually leave my computer on all the time anyway. Is there a big difference in power consumption when mining versus not mining, or playing a 3D video game?

Thanks.

1) only without proper cooling. it could diminish the lifespan but you would probably replace your card before this would do any serious damage.

2) yes by far

Strictly speaking, it will reduce the lifespan of the card, but of the ~10 I've ever had, I've only ever had one die before I considered obsolete anyway, and that one was both over-clocked and over-volted significantly.

Is there a big difference in power consumption when mining versus not mining, or playing a 3D video game?

Mining vs. Idling - Huge difference. Assuming you have a 9600GT or a 8800GT (about the performance level you are getting), you are looking at around 80-100watts extra power consumption.

Mining vs. 3D gaming - I suspect that it will be more to mine than game, as mining will keep the card at 100% load whereas gaming will fluctuate. I don't expect this to be a large difference though.

If I've helped you out, donations appreciated - 1G5NuGN9D6Vax6pGfqQJqPvww1CCJQPjhe
