Very scientific I am sure...
This math is a little dodgy, tho I'm willing to concede that Tech Report is at fault. It relies on ignoring the "multiple" catagories.
I've never seen a card fail from overclocking in all my years of gaming on the PC platform using 3d accelerators (since the mid-90's, and yes, I've been o/c'ing since then). Cards fail from manufacturing and component defects, as well as poorly-ventilated cases and/or clogged primary card cooling systems.
If you try to run an o/c that is greater than what the card can reliably handle, the driver will generally lockup, causing the system to reboot (XP and earlier).
I'm relatively sure that people smart enough to build their own machines and are part of TechReport's community probably know how to keep their systems well-maintained. Just a guess. It's not like we're talking about some comment section on a vendor site.
NV's current problems are a result of chip creep, a thermal issue. While the clockspeed of a chip certainly affects its heat output, even stock clocks can cause a chip to fail over time, especially when there is a defect in the packaging used which exacerbates chip creep, as is the case w/NV's failing chips. Case-in-point: look at all the non-overclocked mobile G84/G86 failures on bog-standard OEM systems.
Other known causes are Vmods and using after-market coolers that are either installed incorrectly or are inappropriate for the card.
Those with the latest AMD cards that changed coolers and failed to cool the voltage regulators learned the latter.

I have atleast 1 card from every gen Nvidia has made and I've only ever had 1 card die, a GF256SE by Herules and it was a memory issue.
I agree with I.S.T on this one, Nvidia has fan crontrol set to way wierd settings for low and high fan speeds. Most users will OC their cards and not adjust these settings which only worsens the problem. Personnaly I keep my fan speed at 100% no matter if idle or gaming.
No doubt. Poorly-installed aftermarket coolers are not the fault of anyone other than the installer, however. Likewise, voltage modifications void warranties anyway, and anyone that is capable of performing one will already know this and have no one but themselves to blame for any failure.
True, but I would also like to point out that a lot of these aftermarket coolers did indeed state support for some of these cards, right on the packaging often-times.
"Most users" don't even know what overclocking is, so you'd be wrong in your assumption.
Sure, they'd be to blame, but that doesn't necessarily stop them from voting in a web poll that their cards failed.
I dont know what to think of those techreport polls. Its hardly a controlled polling enviroment. In my conversations with Nvidia. They vehemently deny any desktop problems with the G92. I have yet to ever see one fail. And I have 3 9800GTX, 2 8800GT, and 2 9800GTX + ((G92B may not be relevant)). The cards I recieve are no different than any editor hardware. I have lost 2 Nvidia cards in my lifetime. a Geforce Ti 4200, and a Geforce 6800NU Modded to 16/6. Both were massively overclocked. My problem with the poll is there are no ways to prove proof of ownership or failure. Your taking alot of anonymous data to heart from it.
*Edit* Heh I just tested it. I was able to vote 5x. And probably could do more if I felt compelled too. Pretty easy thing to manipulate.

Boo for flawed polling! I also have yet to see any G92/G94 hardware failed in the field, and have quite a few friends using O/C'd 8800 GT/GTS's. My own 8800 GT runs @ 700/1688/1980 (albeit with aftermarket cooling - TT DuOrb) without issue.
I voted 6 times just by switching between IE and Firefox.

Oddly enough I've had 4 friends with Nvidia hardware have their cards fail with no overclocking. 2x9800 GTXs, 1x8800 768 GTX, and I can't remember what the last guy had. Wasn't really a problem though they were all replaced under warranty and are happily running them right now.
Noone I know is using an 8500/8600 series GPU though, so can't comment on that. Most of us with laptops don't use them for gaming so most of us have a Intel IGPs in our laptops. [Edit] Whoops, one friend has an Apple notebook with an Nvidia graphics chip. He recently had to send it in for repairs/replacement when the graphics stopped working.
I have to say though that it's quite possible the desktop parts have the exact same problem as the notebook parts, but it's far less likely a desktop system is going to fail if it is indeed due to the issue of excessive heat/cool cycles and the extreme heat possible in a laptop compared to a desktop.

Apparently Dell has joined HP in formally extending another 12 months of limited (gpu-only) warranty.

Don't I feel dumb for buying a Dell with a Radeon 1400 in it.

In NVidia's words:
"NVIDIA will transition from using Namics 8439-1 underfill material to Hitachi 3730 underfill material for the G86 Desktop product skus only. [...] To increase supply and enhance package robustness,"
