I returned the EVGA 1080 TI SC2 I was using, believing it to be defective. Today my Gigabyte Aorus 1080 TI Extreme edition arrived, and its a bit better than the EVGA A =BIT= better... Doing the same basic render, it finished in about 402 seconds, where the EVGA took about 440 seconds or there abouts. My old machine with its 1060 did the same render in 115 seconds. The 1080 should be something like 3 times faster than the 1060, not four times slower, I'm at my wits end here, what gives!? I have just spent £1200 on this new machine, and its considerably WORSE than my five year old machine that cost half as much back then............. I'm honestly thinking of just giving up on rendering all together now, I couldnt afford this machine when I thought it would be a massive upgrade, now its as good as a damn paperweight unless I can get it to run like the numbers say it should =_=

I'm REALLY hoping its not down to the Windows version. I do =not= want to go to Win10
