I run with an OLD nvidia tnt riva, and it runs all my 3d apps perfectly. But as for games it really limits me. I've used the radeon 9800 and it blew me away with it gaming capabillities, but I've never used it with poser. But if I remember correctly, 3d apps have little to do with the video card as most of the work is put on the prossessor. For the most part, any card that supports z-buffering will run 3d apps fine. (Although if I could get a radeon for that price I'd be in heaven! there about $300-$400 or more here.)
