I am a casual miner that uses my gaming rig to mine when Im not playing. I am curious as to how short my GPU lifespan will be using it to mine. I know several here have a dedicated machine(s) that run 24/7. How long is your typical GPU lifespans?

Stock and normal use its expected to last 7 years.
Overclocking it will bring the life down a bit as well as running 24/7 but it should still last 2-3 years if you keep the temps 75C or lower.

By that time the card will be out dated anyway and you would be able to pick up one thats more powerful for 1/4 the price.

GPUs, CPUs, and other devices are designed to run hot.  nVidia chips throttle themselves at around 107C, and I think ATI is similar.

Extreme heat isn't great for GPUs, but keep them under 90-95C and they should last a good long while.  If anything, it's better to keep them at a constant temperature than constantly going up & down.

The design life is long enough that even if you do shorten it's life, you'll replace it long before it dies.

Need high quality, rack mountable GPU clusters for OpenCL work or password auditing?  http://www.stricture-group.com/
