What is the fastest processor I can buy?

Super cheese sandwich

I have two Xeons with 32 cores in total. It can render faster than a single i7 4 cores but the i7 is faster loading for a iray preview. I thought that buying something with more cores would allow me to load everything faster but not. What do you recommend me to make faster previews using iray? If the i7 4 cores is faster than the Xeons I have then will a i9 be much faster than the i7? Thanks for the help

Better invest in a better graphics card. CPU's don't make much of a diffrence, at least in my expirience. I'd say its 90% GPU and 10% CPU in iray.

Just to echo the above, a CPU upgrade might make a tiny difference, but the real clout comes from your GPU. Iray does most of its work through your graphics card, and even if you're not using the Iray preview Daz Studio relies on your graphics card to render the viewport. If you've only got the one card, you could invest in a second, if you have the space. For best results though, you'll want to disable SLI. This can be done via the control panel rather than physically decoupling the two cards.

NVIDIA used to have an article on their site about finding the balance point between the processor and the graphics card. The CPU does preprocessing, and then it hands off the GPU. If your CPU is lightning fast but your GPU is an older card, the GPU becomes the bottleneck. Likewise, if you invested in a pair of very fast graphic cards but installed them on a computer with an older, slower CPU, the CPU pre-processing will low down the rendering. DAZ has the rendering option to use your CPU and graphics card together or separately. You can play with turning things off and on to see what results in the fastest render time. I recently picked up a pair of Titan cards, and when I did, I also upgraded to a 6 core processor and a new motherboard with a bigger bus to keep up with them.

This system should perform respectably, right?  

Intel Core  i7-6700k @4.00GHz 4.01Ghz   32 GB RAM, 64-bit Windows 10

2 X NVidia GTX-1070 8GB

It can be slow or even lock up while navigating around a scene with 3 figures, some"billboard-style" figures, and a terradome setting.  Iray renders take from 2 minutes to 2 hours so far.

@Myds set display optimisation to best at the settings for better view port performance.

I have a 1080ti and ryzen 1080x but depending on the scene it can take a few hours as well to render

Thanks for the tip!  The main thing that pushes me away is the slow viewport performance.

Yes this setting should fix that. If not try "Better"

Also dial the texture resources to Performance.
