How much more would I be looking to spend for something equivalent from nVidia? If it's better or more future proof, I'd be willing to spend a little extra. I'm a bit lost when it comes to video cards now. Newer video games don't really appeal to me so I've kinda lost track of the video card market.
I came across this page while trying to do some research. I see some of the NV cards support H.265 12 bit. I'm not sure if that matters or not for movies.

If it matters and the previously mention AMD cards support it, I'll go for one of those. If not and the NV cards aren't really any better, I'll go for one of the AMD cards.
