I want 3d gaming on my pc, but I have an ATI gpu. I know that you have to have an Nvidia gpu to display this technology, however, if I buy a 3d televesion instead of a 3d lcd to hook up to my desktop pc, since it doesn't need the nvidia glasses technology, will I have to upgrade anything on my pc? I'm just looking for a way to get around having to get a new motherboard and Gpu, etc.
