Thought this was news worthy:
The minor flaw list is getting longer:

The problems do not effect cards fitted with Samsung memory but manufacturers who switched towards Micron chips are probably regretting it.
Overclocking Micron graphics memory on the card makes the problems appear fast with things like checkerboard patterns appearing. However some users have spotted the occasional flickering or graphical artifacts when using the default setting.
According to Guru3D most manufactures are working on a BIOS firmware update for the graphics cards to increase voltage level of the GDDR5 memory.
EVGA, Gainward, and Palit have already issued updates. ASUS, Inno3D, KFA2/Galaxy, MSI, PNY and Zotac have not. Gigabyte did not use Micron memory.

The minor flaw list is getting longer:
Forth design flaw
As I already had some experience with crackling sound on an old configuration of mine, I decided to check the DPC Latency with DPCLat (I am on Windows 7 x64 SP1). To my surprise, I found out that the DPC Latency is around 350-400us when the PC is idle and it is around 900us with spikes up to 1500us when in game or netflix. The stutter happens usually when the spikes occur. I checked the gpu usage and its temperature and all is well (99% usage, 85C peak temperature as per design), with no sign of throttling.
Third design flaw
In another tale of hardware not quite working as expected, there are reports that the Nvidia GeForce GTX 1080 and 1070 Display Port doesn't work with the HTC Vive virtual reality headset. Nvidia markets both the GTX 1080 and 1070 as offering "innovative new gaming technologies and breakthrough VR experiences," so to have this compatibility problem exist, with the best selling PC HMD, seems like a bit of a blunder.
Second design flaw
The second design flaw to hit the GeForce GTX 1080 and GTX 1070 after the fan revving bug, isn't confined to the reference "Founders Edition" cards, but affects all GTX 1080 and GTX 1070 cards. Users of monitors with dual-link DVI connectors are noticing problems in booting to Windows with pixel clocks set higher than 330 MHz. You can boot to windows at default pixel clocks, and when booted, set the refresh-rates (and conversely pixel clocks) higher than 330 MHz, and the display works fine, it's just that you can't boot with those settings, and will have to revert to default settings each time you shut down or restart your machine.
A user of a custom-design GTX 1070 notes that if the refresh rate of their 1440p monitor is set higher than 81 Hz (the highest refresh rate you can achieve with pixel clock staying under 330 MHz) and the resolution at 2560 x 1440, the machine doesn't correctly boot into Windows. The splash screen is replaced with flash color screens, and nothing beyond. The system BIOS screen appears correctly (because it runs at low resolutions). The problem is also said to be observed on a custom-design GTX 1080, and has been replicated by other users on the GeForce Forums.
First design flaw
VIDIA's decision to sell its reference-design GeForce GTX 1080 graphics card at a $100 premium over the SKU's MSRP of $599, is beginning develop cracks, with early adopters complaining of erratic default fan behavior. The GTX 1080 Founders Edition graphics card features NVIDIA's reference lateral-blower-type cooler, which didn't exactly blow us away, in our review of the card. Customers across the forumscape, including on NVIDIA's own GeForce Forums, are complaining of an issue where the fan of the cooler has a mind of its own, and revs up from 2,000 RPM to 3,000 RPM intermittently, and drops back to its idle speed. This, users complain, is particularly annoying if you're not gaming.
The users observe that these sudden and unpredictable spikes in fan-speed are not in response to rising GPU temperatures or clock speeds. Sudden variations in fan-speed are worse than gradual variations in response to legitimate triggers, as it also means sudden changes in noise, which is distracting. Users also observe that you can't even use third-party software (eg: EVGA Precision) to stabilize or override the fan-behavior, as the speed-spikes don't respect custom settings.
