Is 2 GTX 950s in SLI better than one GTX 1050 or 1060?

I built a pc last summer and am now looking to upgrade it. One thing that i have no idea about is the relative value of GPUs between generations; ex. 950 compared to 1050. My current motherboard only has one GPU slot, and I was wondering if I should upgrade my motherboard so that I can run 2 GTX 950s or upgrade my GPU to a GTX 1050 or 1060.

As someone who has had SLI GPUs dating back to the 3dfx Voodoo2 days of the late 1990s, don't bother. Ever increasingly, new games are starting out with poor or zero SLI (or AMD Crossfire) support. This doesn't take into account the increased fan noise and heat output from two GPUs which for me means a lot in an air cooled case, especially in the warm/hot months of the year.

By "poor" I'm referring to poor scaling, or the second card yields less than 75% increase in FPS improvement (in a perfect world, SLI of the second card should be a 100% FPS or double improvement). By zero I'm referring to either never going to have it or a patch coming later to allow multiple-GPUs (which often means crappy scaling).

I'm not sure what happened...

I'm not sure what happened in recent years, but developers seem to have either gotten lazier or just decided that coding for multiple GPU support wasn't worth the additional work (or both). Get a single 1060 6GB and you will be good for several years at 1080p. It performs about like a 980 and is more than twice as fast as a 1050.

Great answer. You just saved me money and labor. Thank you.
