If you can find an OEM Dell GTX 1080 it is a blower style graphics card that will mitigate some of the aforementioned thermal challenges.
I want to purchase a new graphics card for my XPS 8910 running Windows 10 Pro, 64GB RAM. Present card is Nvidia GeForce GT 730. Looking for a recommendation for a replacement card compatible with my computer.  Thank you.George B
