I didn't read through this whole thread, but I am now running a 9700.
Haven't had any problems. Works perfectly. I was worried too after reading through Rage3d, but if you know how to properly set up a computer (which apparently so many don't), this card works great.
I uninstalled Geforce 3 drivers, put in Radeon, installed drivers, rebooted, and everything works fine.
