Nvidia has a list of gpus that work with their 3D system. I've got the GTX 275 which is on the list. I'm considering a 120Hz monitor, but I don't want to jump on the bandwagon too soon, and I don't know if maya works in 3D that way (shutter-glasses). Though this indicates it does??

I don't think I'd get a headache, because the headache's (I think) are caused from constantly switching the depth that is supposed to be in focus. It's like focussing on something right in front of you, then a split second later being forced to focus on the distance. Messes with your eyes.
Whereas maya would be a single focal depth, unless you zoom around or switch viewports, which you are in control of and therefore are expecting. It's like how you don't get carsick when you drive.

EDIT: Yeah, this looks possible!
