LionRender have done an in-depth test of four high-end GPU cards.

NVIDIA introduced the new Pascal GPU architecture with its GeForce GTX 1000 series cards. Powered by the company’s new 16nm FinFET process the company promised the 1000 series to set a new bar in performance over the Maxwell generation reining the market today.
We were very curious how the new GTX1080 stacked up against the familiar top performers in Titan X and GTX980Ti and so we’ve decided to stack the top GPUs in a Blender performance test.
Our test was a combination of data from existing results from the blender institute (thanks to Ton Roosendaal and the team!) as well as our own tests. To perform the test we used we used the test renders provided by the Blender institute. Our methodology was very simple – we opened the *_gpu.blend file, pressed render, wrote down the time it took to complete the renders.
The graphic cards which took part in the tests were:
- EVGA GTX1080 (Founders Edition)
- EVGTA GTX980Ti
- AMR R9 Fury
- TITAN X

This just hurt to read. I had no idea windows 10 did this to my render times. To think I could render much faster by not upgrading my OS. Somebody with skill should look into it. Is there any way to make Blender and Windows 10 work better together?
Yeah, I was disappointed that my new graphics card wasn't a lot faster than the old one. But inbetween was the change from Win7 to Win10 as well. So this is why my new graphics card seemed a waste of money...
I'll do some more testing later, when I'm home and have my 970 handy, but I just rendered the classroom scene on a 960 under Windows 10 (64 bit) in 18m 51s.
Something is seriously wrong with their Windows 10 benchmarks.
Might be related to some problems with the graphics-card drivers on Win10:
"The final conclusion: GTX Ti drivers for Windows10 are broken. Use Linux or Windows7. https://developer.blender.org/T45093
Blame #Nvidia and #Microsoft"
from: https://twitter.com/tonroosendaal/status/732252803494780936
Someone said it got resolved with a new driver version:
"V368.22 big improvements! thanks @nvidiadeveloper almost 100% speedup for me"

I was thinking the same thing. I've not seen a decrease in speed on my windows 10 system. It runs pretty dang fast. I'd be curious the rest of the specs on their system, what they're running at the same time, etc etc.
I think this will be resolved eventually but, yeah, it will suck for a while. To switch to win10 or not... it's a tough one.
The issue with 980ti (and iirc titan) crappy render times on windows 10 was recently solved: https://developer.blender.org/T45093#375989 - I think Lion Render is just using a (slightly) old version of blender. 1080 render times on windows might be affected too, but that issue doesn't affect linux.
Also, the 1080 isn't officially supported yet (https://developer.blender.org/T48544), so I wouldn't take these benchmarks too seriously.
Dual boot with Ubuntu if there are programs like photoshop that you want to use. Or, you can try going all-on linux.
Here is how some different versions of photoshop run on linux:

Just thinking about working with Blender outside of Linux sends shivers down my spine.
@Yassin - Just out of curiosity: Which Linux are you using? (I may move to Linux and am looking for some insight)
Thanks for the comparison. I might try the scene on my computer so we can all have a good laugh ;) I also checked out your prices Lion Render and they seem pretty good!
I'm disappointed, I've never seen such a difference in a benchmark...
Are you disappointed with the way the benchmark is set up, or with the results?
I mean the results, I have difficulties believing that Windows 10 is causing such a slow down with Titan x (I have 2 Titan x on Windows 10).
I did a quick test on my dual boot machine, running Ubuntu 14.04 (Nvidia driver 352.63) and Windows 10 (Nvidia driver 365.1). Both are installed on identical Samsung SSD's.
Both are running Blender 2.77a and latest Blenchmark. The machine is an Intel Core i7 920 2.67GHz, with 24G RAM and two Asus Nvidia GTX 680 cards

While Linux performed a bit better here too, the results are nowhere near as lopsided as those by LionRender. I'm guessing there is something up with the Nvidia driver used. My cards are also quite old, so it's likely any driver bugs affecting them have been fixed by Nvidia a long time ago. :)
See my comment above - the slowness issue with 980ti and titan cards on windows 10 was recently solved, in the latest build windows and linux render times are very similar.
I upgraded all my PCs from Win 7 to Windows 10, and it's good. Installed on SSD, start up times are incredible and it's all very slick. Make sure you get it while it's still free (before 29 July). Since nVidia are constantly releasing new drivers I'm sure any slow downs (if there are any) will be sorted very quickly, especially for their new flagship 10xx series.
Incidentally:
Windows 7, Core i5-4690 (3.5GHz), 16GB RAM, 2 x TITAN Black, BMW27 scene :
2xGPU: 01:59.53
CPU: Slow. Why waste the time?
I spotted Lionrender rencently and thought I'd try their unlimited plan for a whirl to be able to keep on working while my renders are rendering, and I'm getting render times at least 5 times slower than what they're indicating here. I started out with amazingly fast renders so there may be an issue, Still waiting for news from their support since yesterday. Also don't forget this is an advertisement, probably not a completely scientific test.
Phew. Glad to see the WIndows 10 issues have been resolved after reading the comments. Saw the initial chart and nearly had a heart attack! LOL.
Is someone doing new chart with those new drivers?
i know, that my GPU is out of list, but could be helpful for someone.

I was surprised by the difference between Linux and Win10 listed here, so I ran a test of my own. My 980 Ti on Ubutnu 16.04 vs. Win10, each running Blender 2.77a and running Blenchmark 1.05, only yielded about a 3 second difference. Although in Linux's favor, it was hardly significant.
