Gaming monitor on GTX 1070, second "working" monitor on motherboard. Faster that way?

Hey guys

I have a two monitor setup. One monitor is for gaming, the other i use when I'm working.

Now a friend told me you loose FPS in boarderless gaming because the GPU also renders the desktop which is behind the boarderless window. And on fullscreen the GPU only render the game. Is this true? If so wouldn't it be better to run my second monitor on a secondary gpu? Because if both monitors are plucked in the gtx 1070, the GPU always renders the game + the dectop of the second monitor with somethimes monitor software on it and so on.

Would it be better for gaming to use a second GPU for my second monitor? I have two old GTX 660 TI. So I could use an old GTX 660 Ti for this task. But i could also use the motherboard graphics for the second monitor.

Greetings

it hugely depends on what you're doing on your second.

if you're watching a movie on the second you'll most likely lose some performance.

if you got Spotify + your browser with Tom's Hardware open on the secondary this puts so little load on the GPU that you won't lose any performance ingame.

Thank for the answer I use the second monitor while gaming only for browsing and sometimes some monitoring software to check my gpu temps and so on.

But why do I lose sometimes almost 15-20% fps while gaming in boarderless mode? Isn't it because the gpu also renders the desktop behint the game? Or is this not true?

No its not true entirely, will depend on the actual game title itself.
Running windowed can actually use more ram, CPU & GPU power but its not something you word normally notice as a massive performance deficit.
If you have 2 monitors I don't understand why youd run any game in a full screen window anyway??

But yes generally a lot if people with 2 screens , 1 for gaming, 1 for desktop exclusively use the igp for the second screen.

I play all games in fullscreen mode. But if i get some fps more simply by using intel graphics for the second monitor, why not?
Thanky for you help

Would you mind listing your full specs? Also the manufacturer and model number of both your monitors and power supply.
