Games not running at common Benchmarks (GTX 1080)

Hi everyone. I recently built a gaming PC. Everything is working fine, except (seemingly) the gaming. Games run worse than my laptop which has a GTX 970m in it.

Hitman was running at about 25-35 fps at medium settings at 1080p, with lots of stuttering. Same goes for Watch Dogs 2.

Nvidia drivers are up to date, and I used DDU to uninstall and reinstall them.
BIOS was also updated to most recent (if that's any help).
My GTX 1080 is in the PCIE 16_2 slot, because my CPU cooler is too big to allow 16_1. According to many people, this shouldn't matter.

My games are installed on the hard drive while the OS is on the SSD. I don't think this matters.

I'm not exactly sure where to start in fixing this. Could someone give me some pointers?

Specs:

CPU - Intel i7-6800k
GPU - Asus GTX 1080 Strix
Mobo - Asus x99-A II
RAM 32 gb corsair dominator (4x8)
PSU - EVGA Supernova 850 P2
SSD - samsung 850 evo
HDD - Western Digital Blue 1TB

 
Solution
i would move the card down to the next available pci-e 3.0 slot just to be on the safe side.

in the eufi look under tools menu. for gfx card information.

you should be able to find a drop down with the available gpu/pci-e choices.

Someone else asked me to do this as well, but I don't even see an option for "default gpu." Would you happen to know roughly where I can find this?

Also, would this happen to have anything to do with the fact that according to the motherboard manual, the 16_2 is pcie 2.0 while 16_1, 16_3, and 16_4 are all pcie 3.0/2.0? Should I try moving it to another slot?

Not sure why this is, but I moved it to another PCIe slot and it changed immensely. In the BIOS it said my card was running at x1, whereas another slot ran it at x8. I moved some stuff around in my case and was able to fit it into slot 1, and now it's running at x16.
