I am so glad that this knowledge is finally being acknowledge by reputable companies and review sites. I hope the community starts supporting this stuff more, it seems like most are but you still have a few people that haven't experienced it or claim it doesn't exist.
This whole situation reminds me of the whole "input lag" on monitors argument around 5-7 years ago. You had so many people claiming it didn't exist either because they weren't sensitive to it, they never experienced it, or never actually compared a monitor with low input lag to a monitor with high input lag. Now every company measures it on their reviews and it's a very big deciding factor when buying a monitor.
The same considerations should be taken when buying a GPU. Sheer FPS is not the full story.

These results just make me feel as though there's something wrong with their methodology.
Of course it will be. You need to compare a SLI/CF rig getting around the same FPS as a single GPU rig to see the results. The SLI/CF will typically not seem as smooth, and sometimes even a single GPU system getting less frames will feel smoother than a SLI/CF rig getting higher frames. There are a lot of factors... drivers/games/cards/etc.
SLI/CF is not a bad purchase by any means, but if you buy two lower end cards to match or slightly beat the performance of a single GPU card... chance are your "actual" smoothness will be worse on the two cards even if the FPS claims otherwise.

As it should. I just don't think some people quite understand what frame lag does. 7970s in CF are definitely superior to a single one, however if you took a single GPU and directly matched the performance of 2x 7970s then chances are the smoothness on the single GPU would seem much better.
