GTX 1080 too slow, something must be wrong. What am i missing?

[somdow]

So i picked up an EVGA gtx 1080 founders edition and it arrived today. Monitor and other things arrive tomorrow.

in the meantime while i wait for the 4k monitor, i decided to play a few games and benchmark the new card etc.
I tried The Witcher 3 and it was sluggish even on normal. I tried everything ultra(on 1080p) and it was jumping here and there. And Arma 3 was..........arma 3 lol
anyways,

When i installed the card, i removed all drivers and installed the ones from the CD, then saw Gforce Experience with another update and i am now on the latest update.

Then I ran for example Valley unigine benchmark tool (amongst others like 3dmark etc) and looked at the scores/results for Valley here: https://www.techpowerup.com/forums/threads/unigine-valley-benchmark-scores.183712/

I ran the test and my scores are LOW. SUper low.
im talking 1900s score, around there. I see people on the scores list with numbers way higher than mine and they are on single 7 series.

I guess my question is, what am i doing wrong?

PS: Im not a numbers whore but seeing as how witcher 3 and arma showed no improvement, something is
wrong.

Here is my setup:

1080p TV
Asus maximus hero vii
H110 ccooling
4 huge mm fans(top / front /side/ back)
240gb kingston ssdNow (boot drive)
total of about 12TB of hdd space
EVGA GTX 1080 Founders edition( runs main screen & my left screen)
EVGA GTX 780 Founders edition (runs my right screen)
INTEL i7 4770k (stock clock) 3.5ghz
32 gigs of RAM

and a gazillion USB items connected to it.

oh oh and a corsair 850W PSU

and so overall, its not the biggest system in the world but 1900 score is WAY too low. heck i got around 4.5k scores with my 780 as my main card.....

what am i missing?

Thanks in advanced.

What happens if you remove the GTX 780? Normally, you need to run GPU's of the same generation to do what you are doing. Pull that GTX 780 out and see how things go that way.
