Building a new i9 Gen 9 machine, and looking at video cards. Nvidia reigns supreme over Radeon just about everywhere else, but I see multiple posts about problems with Nvidia cards on Vegas. In fact, I was looking at a buying a friend's 1070i. I currently have a R9 380X I could use, but the benchmark is half of the Nvidia. My main interest is timeline performance over render times.
Thoughts would be appreciated.
