And I wouldn't yet say that it's an incredible increase in tess performance based on this article. We have data from 2 benchies one of which only got a 9% increase...
Besides I buy what I think is best for me. I still own 2 radeon HD 5870s.
The point of tessellation isn't to increase performance.
Tessellation allows for much higher poly models in games without a large impact on framerate. It basically allows for a continuous LOD
on any mesh. This kind of LOD has been around for a long time, but usually only on terrain, whereas polygon soup meshes that generally makeup most of what you see in a game would just have a few levels of LOD. When you have LOD levels players will often notice that, where you're walking through a level in-game and you suddenly see a model become much more detailed in an instant. Developers did their best to setup the LOD levels to hide this so it isn't always noticeable, but even the best games still have it. Once you switch to tessellation you have a continuous LOD, which makes the removal or addition of polygons virtually unnoticeable.
Long story short: Adding tessellation to a game just allows for higher poly models and a smooth LOD without the huge performance impact that you would get without tessellation. What tessellation won't do is increase performance on any game that doesn't utilize it properly.
