Yesterday, NVIDIA has released WHQL-certified drivers to align with the release of Overwatch. This version, 368.22, is the first public release of the 367 branch. Pascal is not listed in the documentation as a supported product, so it's unclear whether this will be the launch driver for it. The GTX 1080 comes out on Friday, but two drivers in a week would not be unprecedented for NVIDIA.
While NVIDIA has not communicated this too well, 368.22 will not install on Windows Vista. If you are still using that operating system, then you will not be able to upgrade your graphics drivers past 365.19. 367-branch (and later) drivers will required Windows 7 and up.
Before I continue, I should note that I've experienced so issues getting these drivers to install through GeForce Experience. Long story short, it took two attempts (with a clean install each time) to end up with a successful boot into 368.22. I didn't try the standalone installer that you can download from NVIDIA's website. If the second attempt using GeForce Experience failed, then I would have. That said, after I installed it, it seemed to work out well for me with my GTX 670.
While NVIDIA is a bit behind on documentation, the driver also rolls in other fixes. There were some GPU compute developers who had crashes and other failures in certain OpenCL and CUDA applications, which are now compatible with 368.22. I've also noticed that my taskbar hasn't been sliding around on its own anymore, but I've only been using the driver for a handful of hours.
You can get GeForce 368.22 drivers from GeForce Experience, but you might want to download the standalone installer (or skip a version or two if everything works fine).

Tagged: nvidia, pascal, gtx 1070, 1070, gtx, GTX 1080, 16nm FF+, TSMC, Founder's Edition
Several weeks ago when NVIDIA announced the new GTX 1000 series of products, we were given a quick glimpse of the GTX 1070. This upper-midrange card is to carry a $379 price tag in retail form while the "Founder's Edition" will hit the $449 mark. Today NVIDIA released the full specifications of this card on their website.
The interest of the GTX 1070 is incredibly great because of the potential performance of this card vs. the previous generation. Price is also a big consideration here as it is far easier to raise $370 than it is to make the jump to GTX 1080 and shell out $599 once non-Founder's Edition cards are released. The GTX 1070 has all of the same features as the GTX 1080, but it takes a hit when it comes to clockspeed and shader units.
The GTX 1070 is a Pascal based part that is fabricated on TSMC's 16nm FF+ node. It shares the same overall transistor count of the GTX 1080, but it is partially disabled. The GTX 1070 contains 1920 CUDA cores as compared to the 2560 cores of the 1080. Essentially one full GPC is disabled to reach that number. The clockspeeds take a hit as well compared to the full GTX 1080. The base clock for the 1070 is still an impressive 1506 MHz and boost reaches 1683 MHz. This combination of shader counts and clockspeed makes this probably a little bit faster than the older GTX 980 ti. The rated TDP for the card is 150 watts with a single 8 pin PCI-E power connector. This means that there should be some decent headroom when it comes to overclocking this card. Due to binning and yields, we may not see 2+ GHz overclocks with these cards, especially if NVIDIA cut down the power delivery system as compared to the GTX 1080. Time will tell on that one.
The memory technology that NVIDIA is using for this card is not the cutting edge GDDR5x or HBM, but rather the tried and true GDDR5. 8 GB of this memory sits on a 256 bit bus, but it is running at a very, very fast 8 gbps. This gives overall bandwidth in the 256 GB/sec region. When we combine this figure with the memory compression techniques implemented with the Pascal architecture we can see that the GTX 1070 will not be bandwidth starved. We have no information if this generation of products will mirror what we saw with the previous generation GTX 970 in terms of disabled memory controllers and the 3.5 GB/500 MB memory split due to that unique memory subsystem.
Beyond those things, the GTX 1070 is identical to the GTX 1080 in terms of DirectX features, display specifications, decoding support, double bandwidth SLI, etc. There is an obvious amount of excitement for this card considering its potential performance and price point. These supposedly will be available in the Founder's Edition release on June 10 for the $449 MSRP. I know many people are considering using these cards in SLI to deliver performance for half the price of last year's GTX 980ti. From all indications, these cards will be a signficant upgrade for anyone using GTX 970s in SLI. With the greater access to monitors that hit 4K as well as Surround Gaming, this could be a solid purchase for anyone looking to step up their game in these scenarios.

Yes that's right, if you felt Ryan and Al somehow missed something in our review of the new GTX 1080 or you felt the obvious pro-Matrox bios was showing here are the other reviews you can pick and choose from. Start off with [H]ard|OCP who also tested Ashes of the Singularity and Doom as well as the old favourite Battlefield 4. Doom really showed itself off as a next generation game, its Nightmare mode scoffing at any GPU with less than 5GB of VRAM available and pushing the single 1080 hard. Read on to see how the competition stacked up ... or wait for the 1440 to come out some time in the future.
"NVIDIA's next generation video card is here, the GeForce GTX 1080 Founders Edition video card based on the new Pascal architecture will be explored. We will compare it against the GeForce GTX 980 Ti and Radeon R9 Fury X in many games to find out what it is capable of."

The summer of change for GPUs has begun with today’s review of the GeForce GTX 1080. NVIDIA has endured leaks, speculation and criticism for months now, with enthusiasts calling out NVIDIA for not including HBM technology or for not having asynchronous compute capability. Last week NVIDIA’s CEO Jen-Hsun Huang went on stage and officially announced the GTX 1080 and GTX 1070 graphics cards with a healthy amount of information about their supposed performance and price points. Issues around cost and what exactly a Founders Edition is aside, the event was well received and clearly showed a performance and efficiency improvement that we were not expecting.
The question is, does the actual product live up to the hype? Can NVIDIA overcome some users’ negative view of the Founders Edition to create a product message that will get the wide range of PC gamers looking for an upgrade path an option they’ll take?
I’ll let you know through the course of this review, but what I can tell you definitively is that the GeForce GTX 1080 clearly sits alone at the top of the GPU world.
NVIDIA's Ansel Technology
“In-game photography” is an interesting concept. Not too long ago, it was difficult to just capture the user's direct experience with a title. Print screen could only hold a single screenshot at a time, which allowed Steam and FRAPS to provide a better user experience. FRAPS also made video more accessible to the end-user, but it output huge files and, while it wasn't too expensive, it needed to be purchased online, which was a big issue ten-or-so years ago.
Seeing that their audience would enjoy video captures, NVIDIA introduced ShadowPlay a couple of years ago. The feature allowed users to, not only record video, but also capture the last few minutes. It did this with hardware acceleration, and it did this for free (for compatible GPUs). While I don't use ShadowPlay, preferring the control of OBS, it's a good example of how NVIDIA wants to support their users. They see these features as a value-add, which draw people to their hardware.

Update (May 12th, 1:45am): Okay so the post has been deleted, which was originally from Chris Bencivenga, Support Manager at EVGA. A screenshot of it is attached below. Note that Jacob Freeman later posted that "More info about SLI support will be coming soon, please stay tuned." I guess this means take the news with a grain of salt until an official word can be released.
Original Post Below
According to EVGA, NVIDIA will not support three- and four-way SLI on the GeForce GTX 1080. They state that, even if you use the old, multi-way connectors, it will still be limited to two-way. The new SLI connector (called SLI HB) will provide better performance “than 2-way SLI did in the past on previous series”. This suggests that the old SLI connectors can be used with the GTX 1080, although with less performance and only for two cards.
This is the only hard information that we have on this change, but I will elaborate a bit based on what I know about graphics APIs. Basically, SLI (and CrossFire) are simplifications of the multi-GPU load-balancing problems such that it is easy to do from within the driver, without the game's involvement. In DirectX 11 and earlier, the game cannot interface with the driver in that way at all. That does not apply to DirectX 12 and Vulkan, however. In those APIs, you will be able to explicitly load-balance by querying all graphics devices (including APUs) and split the commands yourself.
Even though a few DirectX 12 games exist, it's still unclear how SLI and CrossFire will be utilized in the context of DirectX 12 and Vulkan. DirectX 12 has the tier of multi-GPU called “implicit multi-adapter,” which allows the driver to load balance. How will this decision affect those APIs? Could inter-card bandwidth even be offloaded via SLI HB in DirectX 12 and Vulkan at all? Not sure yet (but you would think that they would at least add a Vulkan extension). You should be able to use three GTX 1080s in titles that manually load-balance to three or more mismatched GPUs, but only for those games.
If it relies upon SLI, which is everything DirectX 11, then you cannot. You definitely cannot.

The GTX 1080 announcement is starting to ripple into retailers, leading to price cuts on the previous generation, Maxwell-based SKUs. If you were interested in the GTX 1080, or an AMD graphics card of course, then you probably want to keep waiting. That said, you can take advantage of the discounts to get a VR-ready GPU or if you already have a Maxwell card that could use a cheap SLI buddy.
This tip comes from a NeoGAF thread. Microcenter has several cards on sale, but EVGA seems to have the biggest price cuts. This 980 Ti has dropped from $750 USD down to $499.99 (or $474.99 if you'll promise yourself to do that mail-in rebate). That's a whole third of its price slashed, and puts it about a hundred dollars under GTX 1080. Granted, it will also be slower than the GTX 1080, with 2GB less video RAM, but $100 might be worth that for you.
