This is an old thread, but I wanted to share my results in going from a GTX 1060 to a GTX 1080 on an 8 core box with 32GB of memory.

It reduced my UHD render times by about 6%. The same video rendered on a friend’s box is 40% faster. He has double the cores (threadripper) and a GTX 1080 ti.

Without systematic testing it is difficult to be positive, but the obvious conclusion is that a CPU upgrade will net you a better return than the video upgrade.
