Should I turn it on when I have the opportunity?

Tesselation algorithms are use to dynamically adjust the level of detail (LOD) given a specific distance of objects from the viewer. The farther away an object is, the less detail it will get. This can help greatly with frame rates, but not everyone likes it as long distance viewing (in the case of a large world) can look grainy and not well defined.
2GB cards, while not "invincible" are adequate at most of the common resolutions. Many tests show that over 2GB do not produce any real advantages over a 3 or 4 GB solution for gaming.
Your best bet is to adjust your setting to get the best combination of frame rates and image quality that you find acceptable. Since I use a 30" monitor, I turn off AA as I really don't need it. This helps frame rates, but would not be so good on a lower res monitor.
