The ultimate question, Nvidia or AMD?
Well, what brand do you prefer? I am an Nvidia guy myself, but that is because they are better....
For the longest time, I've stuck with Nvidia. I had an AMD (well ATI at the time) card years ago and the drivers would just crash all of the time, I switched to Nvidia and then had a driver crash once every few months.
AMD are definitely better value, but I still can't trust their drivers. Some of my friends have new AMD cards and still have drivers crapping out on them.. Not much fun for me.
Nvidia cards also work really well with Adobe tools, which I use for making the videos
But demm, what about coin mining?
