Rocky 4 with Multi-GPU: which hardware is best for you?

Which vehicle would you rather own: A car or a bus? If you typically only transport yourself and a few others, a car is the better choice—you can easily get everyone across town in one trip, and a car is less expensive to purchase and operate than a bus. But what if...
