I have recentlty built a new computer witht the current specs:

Corsair AX 1200i, 1200W PSU
Intel force 320 series 160 GB SSD (Primary OS disk running windows 10)
Corsair SSD Force Series LE 960GB 2.5'' (Hard drive used for primarly games)
WD black 2 TB HDD 7200 RPM (misc. storage)
ASUS ROG Maximus VIII Formula, S-1151
Intel Core i7-6700K Skylake
Corsair Dominator DDR4 3400MHz 16GB (Running at standard operating hz at the moment 2133 MHz - 1.2 V - CL15 - 15-15-15-36 )
MSI GTX 1080 Sea Hawk X

Now i usualy run 2 monoitors one 144hz 1080p gsync monitor and one standard 1080p 60hz. I primarly use the standard monitor to browse websites and watch videoes. But i have a smal issue. When i play games everything is fine usualy the issue is specificaly with loading screens even games that does not requre much power like for instance dark souls 3. when the loading screen shows and i have some form of video playback(Youtube,netflix, VLC and etc.) running on the secondary screen the video playback stutters for the whole duration of the loading screen then goes back to normal afterwards.

I was wondering does anyone know a possible solution for this issue ? what i was thinking about was using my old gtx 660ti to run my secondary screen. can that be a solution ? or will other botlenecks in the system cause issues ?

Answers regarding my suggested solution or any other suggestions would be greatly appriciated.

Thank you in andvance and sorry for bad grammar (English is not my first Language).
 
Solution
A second graphics card is a bad idea. It's not the GPU that is overwhelmed, but either the CPU or storage. Or it's just bad coding from teh game makers.
Adding a second GPU will only add to your issues.

ok, are the movies on the same drive as the game you are playing?


if so put the movies into a different drive than the one which has the game installed onto

I suspected the storage myself that was why i addedd a secondary SSD to run my os with a fresh install and it did not help. it could be my cpu but i seriously doubt that since it does not run over more than 60 % load and happens regardless of the game and the issue is not reflected in the the game only on the secondary screen.

Jupp idlie around 30 C and usually runs around 40 - 60 under load to heavy load the coling bracket on my (Corsair H100i) is never over 36 degrees.

And since the stutter is only in the video playback not the loading screen and not anythging else that is noticable i suspect it has nothing to do with the CPU

turn off gpu acceleration on the video playback software you use

I have been tinkering abit with this now but sadly none of the sugestions has helped i have however discovered that the issue is non existant when i run the game in windowed or borderless windowed mode so something with the full screen is creating the issues.
 


Window borderless will prevent g-Sync from working so i would definitely stay away from that. Honestly, i'd just rather use Win+P to disable the second screen altogether of just deal with the stutter while loading to keep using G-Sync.
