attention PNY GF4 Ti4400 users.....question for ya

[blurredvision]

I'm going to pick up my very own PNY GeForce4 Ti4400 card tomorrow, and it comes with the free "3D" glasses. I was just wondering, are these even worth anything? I mean, if they are packed in free, they can't be too good, now can they? I've heard they are all crappy, but I was just wondering if they are even feasible to use in games.

EDIT: Also, any word yet on if any Visiontek owners giving up the tech demos? I'd like to have 'em too!
