MacPro 3,1 & GTX 1080 Ti, possible ?

[Mark Spencer]

Hey all,

I was wondering if it was possible to upgrade my old early 2008 macpro 3,1 with GTX 1080 Ti's graphic card and... it doesn't work ... for the moment...

I'm running with El Capitan OSX 10.11.6 (15G1611) and I just replaced my Sapphire AMD Radeon HD 7950 Mac Edition by ASUS GeForce® GTX 1080 TI 11GB Turbo for having a better workflow with my video softwares (like Premiere Pro & Resolve).
I've made installations of latest CUDA's Driver and Web Drivers (WebDriver-346.03.15f09) as mentionned with these attached screenshots.

So... If I upgrade to High Sierra OS with the related webdriver, is there any chance to give GTX 1080 Ti supporting by my MacPro 3,1 ?!
Or do you have any suggestions to solve this problem please ?!
Thanks for all your feedback.

Kind regards,
