I installed Sunday's Rawhide on mu office computer, a 32 G Intel 3770K with Nvidia video card.
The good news is: Noveau hasn't wedged yet. The bad news: The system responds slowly, the cursor sluggish and jumpy. A rather disagreeable experience.
So I am back to Korora 19 with the Nvidia driver on the same hardware. It is quick, smooth, and responsive.
