NVIDIA GeForce GTX vs. AMD Radeon graphics cards.
Fedora 28 and beyond
it appears that
Fedora 28 and beyond DOES support NVIDIA cards
Install an NVIDIA GPU on almost any machine
use Fedora 28’s brand-new third-party repositories
This process works for any UEFI-enabled computer, and any modern (UEFI-enabled) NVIDIA GPU.
It may be enough if the maximum power output of the power supply meets the minimum recommendation of the GPU.
Use your discretion to determine your requirements if you’re using a particularly power-efficient or power-hungry setup.
Cinnamon vs. Cinnamon (Software Rendering)
I just read
“Cinnamon (Software Rendering) the only characteristic is that it uses software rendering to do more of the graphical work, like drawing window borders, moving windows, the bar, etc.,
“The Cinnamon has Hardware Acceleration capable techniques available. Is more eye-candy and powerful that the software render, since it uses a dedicated graphics card to make that all the effects looks fluid and fast. The advantage of this is that you can fallback to no-effects environment without problems. …
“The only real downside to using hardware acceleration is if you have a buggy driver, you can run into more glitches in the graphics (software rendering is more predictable).
“For example, with Linux Mint 17, I see issues with Chromium not fully repainting the screen when re-sizing the windows (if I try to use hardware acceleration). I can’t perceive any speed difference between the two, though I typically turn off all “eye candy effects” regardless.”
“If your driver is very buggy, I would imagine hardware acceleration could cause crashes, or your whole system could even run more slowly. Otherwise, I just try the acceleration first, and drop back to software rendering if I see any weirdness (crashes, lockups, repaint issues, etc). Hardware acceleration is great if the the drivers work.

(Makes me wonder if it would have helped me to switch to Cinnamon (Software Rendering) with the GTX graphics card – though I was not using any of the “eye-candy” special effects.)
Sept.2015: I got a 42″ 4K monitor. The lower half shifts right a few inches or more and right back in just a split second – once in a while when scrolling or dragging in a window. I can only hope it does not get worse. . . . – 2015-09-24
it got better, not worse. I u8pgraded to Fedora 24 and , later, 28 also.
