Good day.
I know that you, there in west have better hardware. I can afford only quadro 2000 and quadro nvs 315.
This, the last one does compute in 6 hours and 47 minutes a task from Moo Wrapper !, and quadro 2000 about 1 hour and 50 minutes.
I don't know yet, for seti how much time it takes for nvs 315.
I had 3 GTX, 560, 280 and 470 -- but first 2 after 5 mounths had black images and 470 after 2 weeks, had artifacts on image, so where compromised.
Purchased from second hand store, those quadro, specified above.
Are quadro more resistant -- better made ?
I do computing for BOINC, about 13 hours per day, every day.

No, you probably got a bad batch.
Most GPUs I own, have been able to run for 9 months straight.
Most of them failed, because of me grabbing them out of their socket, and perhaps some static electricity killed them.
I've had to RMA a lot of GPUs; all perfectly working samples, that just died.

The best ones, are the ones where the chips and pins aren't exposed, and where it's not easy to blast them with static.

Static, maybe.
