using 2 GPU's for 2 monitors

takithes · July 26, 2019

So, i have a little issue with my 2 monitor setup. The other monitor is kind of old and only has DVI and VGA connections, and i went ahead and bought the radeon 5700 xt, i thought it wouldn't be an issue to just use 1 monitor, but as i've been playing for a while and doing some other stuff, it's getting pretty annoying to only use 1 monitor. So, i have a spare gtx 1060 6gb card just laying in a closet, and i was wondering would it be any harm to just stick it in with the 5700 XT, to use it for the second monitor, and yes, i know i could get an adapter to plug it in to the 5700 xt, but im just curious, would it have any effect on the PC's performance in any negative way?

That would be driver hell, having both nVidia and AMD GPU's in one system. Just buy an adapter for your 5700XT, much less headache and actually guaranteed to work. I had multiple GPU's in my system, mixing brands is a fast road to nothing working. Even mixing architectures isn't good.

it *should* work. Windows needs these sort of features for laptop switchable graphics. I once used two nvidia cards bc i had too many screens and that worked flawlessly.

But even different drivers shouldn't be a problem since they just bind to the hardware they belong to.

As long as you keep your primary display on your main GPU, windows will use it to render so there shouldn't be much of a impact

That said windows is not very transparent when it comes to troubleshooting stuff like that.

Your time probably costs more than the 1$ adapter you need...
