Running two video cards in SLI is absolutely incredible. When I do a render with the processor only, it takes 2 hours and 39 minutes to render that desk. When I do it on the threadripper, it takes 59 minutes and 30 seconds. When I use one video card and the processor, it takes 12 minutes. But when I use two video cards and the processor, it takes just over 5 minutes. I still have yet to try two video cards in SLI with the threadripper processor but I suspect it will be three and a half for 4 minutes. I really wanted to try with the Vega but SolidWorks visualize does not work with that card.
