More cores or higer processor speed for Photoshop 3d?

I've been trying to find a definitive answer to this question and haven't been able to find one so I hope you'll be able to help here. Is an i7 4820K processor with a clock speed of 3.7 ghz better than a 4930K with a slower clock speed but an additional 4 cores. Is it worth spending the money on a 4930K when I see my CPU meter not maxing out on all cores while I wait for a long time to move one piece of a 3d split extruded model in Photoshop CS6 with my 4820k processor. Can more cores really help with this issue when I don't appear to be fully utilising all the cores I already have?

PS No emoticon for tearing hair out here I see..

What you might need to make it faster depends a lot of the model you are working with and what is making it slow.

You might need more RAM, more VRAM, a faster CPU, or a faster GPU depending on the details. Or you could be hitting a bug in a driver, or a slow part of the Photoshop code we just haven't noticed before (which I did last year on a model with about a thousand materials, and then had to go fix :-) - but we're constantly improving it.

In general, more cores are better for rendering and painting. More RAM and VRAM are better for more complex models (more polygons). Faster GPU is better for more lights (or IBL) and complex surface materials.

SImply moving part of the model could be dependent on rendering, or just the speed of RAM (to move or change the data).
