All the benchmarks I can find are comparing this against the GTX 980. I'm curious how it compares to a 980 Ti.

I'm sure some of those expensive cards have extra features, but the pricing differences are still crazy.
Meanwhile we have no problems with an office running on 950Ms and 780/980 GTXes, except for some weird driver bugs that only occur on the single Quadro machine that we keep for reference.
AFAICT, PassMark's GPU benchmarks are most often used simply because it's usually the first Google result for "video card benchmark".
