I've had great experience before with a 4600 Ti too, but unfortunately the card went to the great GPU up in the sky sometime back.
My experience with GF6 cards and Win98 has not been as positive. The two don't seem to play well- very buggy and lotsa crashes. Does this have something to do with later revisions as your post seems to indicate?
How do the Radeon 9500/9700/9800 play with Win98? Are the Win98 drivers any good for games from about 1998- 2003? As problem free as a Geforce 3/4?
How would a 9600 Pro/ XT compare in all this?
Or an FX series card- like a 5800/5900? I know they suck at DX9, but I'm gonna use it for DX7/8 mostly. And I'm hoping Win98 support on them is better than the otherwise superior GF6 series.
I would like something more powerful than my Ti200 so that I can max out all the oldies with AA/ AF.
