ATI 3D solution so far is IZ3D. Its free to try so if you have a 3D monitor (Zlaman) you may as well give it a go. http://www.iz3d.com/
Its not as good as 3D vision but it uses polarized glasses so the glasses are dirt cheap. Its not bad by any means, you just don't get a sense that anyone is updating it or testing games with it.
I think you meant me, as I was running a GTX295 and 3D vision till 3 days ago. I have a GTX470 SLI going now :)
At the same time when I switched to the 470s, I set up a Acer 3D Vision projector and a 92 inch screen. The projector runs at 120 hz but is 720p...so my 3D performance went up by 100 %.
Prior to this I was using a 3D DLP which needed 1080p X 2 processing, but was only showing 720p to each eye (checkerboard) . Now with having 720p resolution shown to each eye, with 720p x2 video processing...I've realised that 1 GTX470 would have been enough.
