I personally like 3D a lot, but find 3D Vision has some big advantages. The biggest one is actually a mod community that has fixed many games to work near perfectly in 3D that normally don't work well. http://helixmod.wikispot.org/gamelist
The 3D monitor you are looking at is HD3D and only useable for AMD system. It still may work nicely for the games that do support 3D, but there are a lot of games that don't and would benefit from modding community.
