Is the iMac 27 running at 5K resolution good for rendering with blender?

GPU: AMD Radeon R9 M295X with 4GB GDDR5

CPU: Intel i7 4.0ghz (Turbo 4.4ghz)

    $\begingroup$ Imacs and Mac "Pro" with AMD processors are not great for rendering in cycles using GPU. $\endgroup$

Your "best" is hard to answer. Blender can use CPU and GPU for rendering. Here's an overview of a hundred or so CPU and GPU test renders: http://blenchmark.com/benchmarks-overview

Here's a sample of the data, where shorter lines mean faster renders: enter image description here

In Cycles rendering, when you select GPU rendering, several of the initial file preparation steps are completed on CPU, then image rendering begins on your GPU. So a fast GPU is great, but a fast CPU still helps.

So "best" is pretty much always the most CPU, RAM, GPU and VRAM you can afford... but the benchmarks will help you see where economies exist.
