Cheap used 1070s

(moderation:
Cryptominers are dumping GTX 1070's on fleabay for as little as $225 bit it now. If anyone's looking for a cheapish upgrade GPU this might be the time to get one.
I'm debating replacing either my GTX 980 or RX560 cards. I'm not entirely sure the former would be worthwhile though for only ~25% more credit on the box, and looking at nominal TDP I'd need about 2 years to break even on power consumption. It'd definitely speed up the box with the 560 a lot more but it'd also draw a lot more power. That box is old enough it's only got PCIe2; do the current apps care about PCEe bandwidth much? I know the BRP ones were very sensitive to it at one point.
I have two cards each in two

I have two cards each in two boxes and the loss in performance compared to the same card in the same box is extremely minor on the current Einstein application. I think that suggests the current application is not very dependent on host bus bandwidth. The cards in question include a 1050, 1060, 1070, and 2080. I remember the days when boxes which had cards sharing host resources got pretty severe performance loss.
I think you'd get a lot out of a 1070 on Einstein. There is one sitting on the floor next to me as I type, which will go back into the box in the slot the 2080 is occupying when I run out of 1039L tasks in a day or so.

Nope not a bit for crunching only, gaming YES, crunching nope not enough to offset the differences in each workunit.
Not even for gaming actually.

Not even for gaming actually. There was a more detailed report but I can only find this now: https://www.pugetsystems.com/labs/articles/Impact-of-PCI-E-Speed-on-Gaming-Performance-518/
https://www.gamersnexus.net/guides/2488-pci-e-3-x8-vs-x16-performance-impact-on-gpus
The conclusion was same though. PCIE3 x16 and x8 doesn't make much difference. PCIE2 is just half of PCIE3. So long as it's on x16 it should make almost no difference as well.

I have had a GTX 1070 and a GTX 980 fail, (EVGA and Zotac). Both were replaced under warranty (neither ever overclocked).
I have had other GPUs fail regularly (even a GTX 750 Ti that never got above 60 C). My experience is that video cards used for crunching purposes last between one and two years, so I would discount used ones accordingly.
My experience is much more

My experience is much more positive, no GPU has failed early on me because of crunching, it includes X1950, 2xGt8800, 3xGTX 260, 2xH7950 (still crunching after six years, fans replaced many times), 1xHD7870 (still folding), 2xGti 660 (over four years until become obsolete in any project, one of them with fan just failing at that moment), 1xGTX 750 (still ON) and my two GTx1080 are now two years old and look ok... knocking wood :)
So i've just purchased one second hand GTX1070 to test my luck :)

I probably just had bad luck. But I did well on the replacements. Zotac replace the 1070 with a V.2 version, which probably eliminates the weak spot; I am sure they do not want to replace cards under warranty. And EVGA did even better for me, replacing a GTX 980 (no longer in production) with a GTX 1070. It is a great card.
I hope they last this time. The performance gains are getting hard to come by now, and I want them to last a long time.
Good luck.
Mine's been generally good

Mine's been generally good keeping cards in use for 3 or 4 years before retirement. Of my cards (2x GTX 260, 1 Radeon 5850, GT560, GTX 770, GTX 980, GTX 1080, RX560), I've had one fan failure on the 5850 after about 2 years and a complete GPU failure on the 560 after about 3.
