For general performance increase, less laggy modeling on high poly, and rendering speed increases.

The Blender UI is still a problem on big scenes but there is something in the work for Blender 2.77.
May you check on https://builder.blender.org/download/ for a daily build.
Make sure you have VBO enabled in User Preferences and use Opensubdiv in Subsurf modifier.
For render performance you are limited on CPU, except change the whole system, but not on GPU.
If your mainboard support it, get a second GPU and voila, 200% performance.
Use big tiles on AMD GPU, best is 1-2 tiles.
If you render HD set 1920x1080/540 in tile settings.
