Well, I finally got my hands on two GTX 1070's and you guys know what that means. As soon as I finished up writing about the second card, I jumped right into SLI testing. With the card availability being tough getting two matching cards might be tough, so before you do that I thought it would be good to see just how much you can benefit from running two cards. On top of that, I wanted to find out if you are better off getting a single GTX 1080 over the GTX 1070 pair. So I ran the cards through our normal benchmark suite. Unlike a card review, though, I jump right into the testing and for the most part I let the numbers speak for themselves. So hang on.
