Ordered a founders edition evga simply cos I couldn't wait until the 17th for the ftw version... Sad. Patience is a virtue and all that, obviously skipped me when the genes were being handed out.

Send it back. The FTW is both cheaper and appears to have dual 8-pin power connectors. And the cooling surely can't be worse.

For my needs I think the founders edition will be fine. I just want it NOW! Set for Tuesday delivery but everywhere is still showing as pre order atm.

The ftw edition is only 20 quid cheaper, if it was more I'd definitely wait.

Just ordered 3, yikes, oh well it's only money......

By default the GeForce GTX 1080 supports two GPUs in SLI – as games have evolved, it has become increasingly difficult to provide beneficial performance scaling with 3 or 4 GPUs, and as such 3-Way and 4-Way SLI configurations are no longer recommended.
Not impossible mind you, simply not recommended. To unlock 3-Way and 4-Way SLI functionality, enthusiasts will need to acquire a free "Enthusiast Key" from a NVIDIA website. Simply run the key software on your PC, follow the steps, and you’ll unlock 3-Way and 4-Way SLI functionality.

Ha ha, you realise sli is limited to 2 cards with the 1000 series?

Where did you order from out of interest? Was it still pre order?

Yes, two for my main PC, and one for the other.

Ordered from PCS as an upgrade. (Didn't say pre-order).

"We are now processing your order and it will be dispatched as soon as possible."

Am I right to assume that a GTX 1080 with dual 8 pin connections will provide better performance? (higher clock speed, more room for overclocking.........)

Yes. Though the cooling will be important as well as even with 1 x 8 pin the founders edition runs into thermal issues.

From what I've read, flat out yes. The founders edition has an absolute ceiling which reduces overclocking potential, it's limited by a 5 + 1 phase power design.

Most of the manufacturers custom cards use 10 + 1 or upwards. Although there will obviously still be a ceiling for overclocking potential, the increased phase power plus extra cooling should provide higher stable overclocks.

There's quite a good collection of pictures of each custom PCB showing the phase power setup http://videocardz.com/60547/comparison-of-custom-geforce-gtx-1080-pcbs

The hydro GTX 1080 EVGA seems to have 2 x 8 pin connections. Since I am looking at a liquid cooling system the thermal issues hopefully wouldn't apply to those GPUs

GTX 1070 scores are out!

Scores vary from bench to bench and game to game, but it seems to be broadly what was expected - roughly GTX 980 ti performance.
http://www.techspot.com/review/1182-nvidia-geforce-gtx-1070/page5.html

Seems to acquit itself in DX12.
http://www.gamersnexus.net/hwreviews/2453-nvidia-geforce-gtx-1070-founders-edition-review/page-3

Though techspot tell a different story:
http://www.techspot.com/review/1182-nvidia-geforce-gtx-1070/page4.html
I think they ought to be clearer about which bench they used, since while I've not played Ashes I'm aware it has a number of different scenario benchmarks designed to abuse the GPU and CPU at a range of different levels.

This may shed some light:
http://hothardware.com/reviews/nvidia-geforce-gtx-1070-review-high-performance-lower-pricing?page=5
It suggests the 1070 does its best work relative to other GPUs in the 'heavy batches'. The 980 ti there seems to be a Strix, which is one of the good ones.

Hexus haven't been the best (in my opinion) at keeping up with the DX11 vs DX12 benchmark issues, but they have done a bang for buck chart:
http://hexus.net/tech/reviews/graphics/93050-nvidia-geforce-gtx-1070-16nm-pascal/?page=13
The pricing is the founder's price, which in some ways is conservative as it might pay a touch less for a decent factory OCed one. Not the most in-depth review but it's a nice twist.

Just want to ask you guys...........

About the SLI bridge.

My motherboard is an ASUS® RAMPAGE III EXTREME: 3-Way SLI & CrossFireX, SATA 6.0GB/s, USB 3.01

Now I'm going to need a bridge to connect the two cards together, and according to the Rampage manual I need to use slots 1 and 3 to maintain the x16 of the PCIe slots, if I use slots 1 and 2 the PCIe will drop to x8 on both slots (something I don't want to do) as I want to achieve maximum performance from these cards.

Having done a fair bit of searching about I believe I need the 4 slot 81.26mm bridge, can you guys confirm this ?

Also it seems the 3 different size bridges are not available yet, I would have thought they (Nvidia) would have sorted that out

Yeah i cannot find anywhere selling the SLI HB Bridge yet, guess it might come out with the GTX 1070 release at a guess.

Like steaky says you can probibly use the one that came with your motherboard for the time being you just wont get the advantage of the increased bandwith.

Theres a SLI section here http://www.geforce.com/hardware/10series/geforce-gtx-1080 it has a bit to help you with Sizes. You have maybe seen this already though.

Hope this helps
