I've been mining on my AMD 290x for the past few days - I brought it for gaming, so I don't need to get a return on the hardware, and the heat generated is useful too - it keeps my apartment a little warmer. Looking at a profit of around $8 per day at current difficulty, which is a pretty cheap heating solution!

That's how I looked at it. Buy a nice graphics card for gaming, use it for gaming and computational experiments, and have it mine while idling to regulate the heat in my apartment for cheap, or even at a small profit.

Might kill the GPU faster than gaming alone, unfortunately[0].

I just bought 3 290x cards for this purpose. Right now they pay for themselves in 2 months.

It's certainly more risky when you are buying hardware only to mine - although I guess that is bounded by the fact that even if FPGA or ASIC miners were to make it unprofitable, the GPUs are still valuable and you can sell them.

Yes, there is risk in buying dedicated hardware but the risk is quite reasonable. The R9 290x GPUs are brand new and in high demand. If for some reason the altcoin market collapses I can sell them close to their original cost.

Do you mine on linux with cgminer? I'm having terrible reliability issues. I have to restart cgminer every hour or else it crashes. Even with this measure, it crashed yesterday night and I sadly lost mining time :)

Why not write a script to get called by cron to check up on things?

"I" meant "cron". The system does this on its own, but it's still a cheap hack. I'd like the crashes to be more predictable, but maybe this is the best I'll ever do. I've spent enough time setting this up already, other things to do!
