Nope, I actually do some gaming. And SLi can be quite useful, hence my 980Ti setup I had for a while
I suppose if you was happy with the state of SLI, then going SLI 1070 is definitely a good option.
I personally love sticking a game on and for it will always work as it should. I have found SLI and Crossfire to mean having to wait a while or in some cases no support at all.
Maybe SLI has improved recently though. But last I checked Gregster was not happy with it and went back to a single card.
