So just out of curiosity I went and started pricing out a system with the specs of that particular configuration. It's difficult to get a direct 1-to-1 comparison, but suffice it to say, if you're shopping for that performance with that monitor, you probably won't get a better deal than the iMac Pro, regardless of configuration.
You could easily get an EIZO monitor in the mix and it is a better than the iMac Pro's monitor. I think if you need a single workstation, the iMac Pro may be tempting. But the cost is pretty high considering I could by three fully loaded 5K iMac's for the same price. And use two of them as part of the render farm. I'm an owner in a studio with about a dozen animators. And although the performance is incredibly nice on these iMac Pros, the cost is high for what you get overall. Instead we would rather buy three regular iMacs and build a bunch of headless Hackintoshes for a render farm (which is what we do).
