Need to see more proof imo. They said the same with standard gtx285 being capable of going 4 way.
Uh no, they never said standard GTX 285 could do that, which is why they came up with special GTX 285 Classified cards that could.

Scuttlebutt is that nVidia is looking into 4-way SLI as an extension, since more MOBOs are becoming four-slot capable. As of now, though, you have to have a specially-designed set of BIOSs to support the extra interrupts the PCIe controller needs and the teaming coordination across four seperate slots (Quad currently only uses two, and of course three for Tri-SLI).

So, nvidia already has a very limited amount of these cards produced for distribution, and here you have a vendor hogging 4 puppies for sh1ts? Wow, good stuff.

Really, It would take a few minutes to press print screen on a bench result, place on mspaint, and upload it to an image host. (or in 3dmark's case, upload an orb, or a GPUz verification)

vs several minutes spent in changing the CPU cooler, and taking pics of it.

4-way CrossFire capable motherboards have been around for close to half a decade. So those issues are long ironed out.

That is rather pessimistic. Watercooling and overclocking three cards would yield much higher frames and higher benches. Four has no relevance unless you are folding. People that like to spend large sums of money care about performance too. There are always the ignorant too. Like those who buy a 5970 to run one 1680x1050 LCD.
It depends.

For gaming, some of us demand a certain level of performance. Me, I know for a fact one of my cards can easily handle my native res without breaking a sweat . . . but I can't settle for anything less than x FPS at my native res . . . and I also prefer to game with all the eye candy on, too . . . I'm just a bit goofy like that.

Do I know multi-GPU doesn't scale well? Yerp. Does it also depend heavily on the game? Yerp. Does it have more of an imp0act at higher res and with the eye candy enabled more than not? Yerp. Does it bother me that some might consider it a waste? Not at all.

But. Unlike most others, I also put my GPUs to work when I'm not at home or gaming . . . F@H keeps them busy.

That only happens if both are at stock. ;)
Both of us knows that benchers rately leave their cards at stock.

Must be fun to cool. Specially the two in the middle.
My immediate thought as well. Actually there are three with the fan completely blocked.

2000w of PSU needed and probably a min of two 360mm radiators and two or three pumps for proper cooling via water.

Na, the PCBs have that cutout in the PCB, so the top card (closest to CPU) will still get a little bit of cool air through that.

OMG Evga is B@llZors for even trying this, the heat the heat the heat holy reactor of a power supply, this is more stupid than my setup Evga is 1am3
Fanboi out-

Ok, seriously less than 1% of users will use a 4x SLI/CF setup and those that don't use it don't understand why they do it(not to grill hotdogs).

Probably EVGA's own Classified SR2. 1200W continuous, 1500W peak.
Looking at the picture they used 2 different PSUs. I recognize modular connectors from an Antec quattro 1200W, and a Corsair HX1000W.

The SLI bridge connector doesn't look right. Why does the 'bottom' card have two connections and the one above it only have one? Surely it should be the other way around? Unless they are connected out of sequence? (1-2, 2-4, 4-3 maybe?) I guess we now know why the PCBs for these have extra vent holes in the back. :D

Because it's an SLI of two SLI arrays.


In 3-way SLI:



With Quad-SLI:



So 4-way SLI is implemented like Quad-SLI, albeit over four physical cards. In that 4-way SLI pic, card 1 and card 2 are like GPU1 and GPU2 of card 1, while card 3 and card 4 are like GPU1 and GPU2 of card 2. So the two sub-arrays are linked.

From all I've heard about their development and dealings with TMSC, they brought it on themselves. It does suck for the industry as a whole.

Interesting how chip design sounds a lot like software design, which share similarities with legislation and sausage making. It ain't pretty.
