Hello all,
I was wondering what people meant by "SLI". I've just started getting into computer technology, by that I mean gaming with a full on gaming pc. I am tempted to get a new GTX 970 to slightly increase performance, even though I have a GTX 960 already. I was browsing a life hacker article (http://lifehacker.com/5972503/what-should-i-do-with-all-my-old-outdated-computer-parts) and said I could reuse the GTX 960 as a dedicated graphics card for PhysX using SLI, and that's where my question comes into play. So, to recap, "What is SLI" and "Could I SLI a GTX 960 and a GTX 970?" (ps I have a i5-4690k w/ a ASUS z97-A)
