Not necessarily. One advantage Nvidia has over AMD is that SLI can be forced onto most games even if they don’t support it. This only works for AFR mode, but in that mode you practically have two cards churning out alternate frames twice as fast. In practice, the cards sometimes have arguments over who goes first, causing out of sequence renders which results in microstutters.

Right, but I'd say it's better to buy a single good GPU and to start playing around with two. You save on electricity and get better performance, especially when we're talking about a GTX 1070 here.

And a person who doesn't know what SLI connectors are used for is probably not tech savvy enough to care about things like these.
