Hi, as you can from see from my previous posts I installed Linux in all my machines. Now I have a PC with an I5 6500 (with Mint on it) and I’m upgrading the GPU. So, do I just open it put the new one and connect the cables? Or do I have to do some thing first? Thank you for all your help.
You’re thinking of firmware, not drivers. To make a GPU work, you need new enough versions of the kernel, driver and firmware. The open source drivers for Nvidia GPUs are still slower and less featureful than the proprietary ones.
