Sorry guys, for the lack of information when I posted my question. What I would like to do is build an affordable PC system for 3d gaming and watching 3d movies. I found out that passive 3d is more relaxed for your eyes and brain and has cheap lightweight glasses so that would be the thing for me, but the videocards that I found on the internet only support active 3d, the most popular one is from nVidia. I am surprised that in computerstores here in the Netherlands very little people can provide me with information about this subject. So I really hope someone here can help me out. Thanks in advance.
