It would fall somewhere between the 4690k and 4790k. In this after effects (cc) bench, the 4690k (stock) took 42s, the 1231v3 is essentially a 4770 and the 4770k (slightly faster) took 35s and the 4790k took 31s. All these were at stock, the 400mhz difference between the 4790 and 4790k (since the k has higher stock clocks) was 3s. Both the 4690k and 4790k can be overclocked for better performance, the xeon cannot.

I would say a more accurate time for the xeon would be 36s since it's slightly slower than the i7's. Even the stock 5960x only did 22% better than the 4790k with twice the cores and double the threads. A lot of that lacking performance comes from the slower clocks of the 5960x. Bottom line if you want to overclock, the 4690k or 4790k will be the choices. If not looking to overclock, you have the 4690k (no point in paying for the k if not overclocking), the xeon would be next best and the 4790k would be the best choice.
They're priced in order of their performance. Nothing cheaper is going to be 'better', performance dictates price so you can always go cheaper and sacrifice performance along with it. An i5 4590 would likely do around 43-44s and costs $195. These prices are pcpartpickers with shipping factored in. If you're close to a microcenter you can get most of these cheaper. $200 for the 4690k and $280 for the 4790k but they're in store pickup only and they charge tax.
$235 4690k - 42s
$250 1231v3 - 36s
$334 4790k - 31s
