I installed a Nvidia GeForce GTX 2070 Super (https://geizhals.at/msi-geforce-rtx-2070-super-gaming-x-trio-v372-257r-a2091022.html) in my system removing a GTX 980. The system has a dual boot with Win10 and elementary OS 5. Both system were using the nvidia native driver. There was no extra effort neither in Windows nor elementary OS. Windows took about a minute to switch to the correct driver after starting with 1024×768. Elementary OS wasn’t interested at all in the change. Conclusion: Using a GeForce GTX 2070 Super works like a charme under Windows and Linux. At least for me and my system configuration. So please don’t blame me if you are running into troubles.
