One of the reasons why I upgraded my graphics card to an Nvidia GTX 970 was because I wanted to try SLI. Nvidia SLI support is known to be better than AMD Crossfire and GTX 970's supposedly low power consumption would make them fit in my small chassis. In this article I'm going to talk about how well my decision has turned out to be.
Firstly, I tested how two of these cards would work together in SLI. I got this opportunity because one of the cards I originally bought have a lot of coil whine, and Amazon sent me a second card add a replacement. I had a lot of time to and the defective card do I used that time for my advantage.
While there were definite temperature related issues with two MSI GTX 970 Gaming cards almost touching each other (I later found out that the second card had a even bigger issue where the second fan on it would not spin up at all), I was even more disappointed to find how bad the driver support for SLI was. Both Call of Duty Advanced Warfare and Far Cry 4 misbehaved and were unplayable without disabling the second card. Additionally, even though Crysis 3 had amazing FPS, it wasn't that smooth. While I'm sure these game specific issues - not sure about Crysis though, as it is quite old - will be ironed out eventually, I felt that, in reality, Nvidia was no better than AMD. The green side wasn't as green as I wanted it to be. Read more about that experience here.
