Thanks for the replies and driver links. It definitely seems like it ought to work, I'm just trying to get some confirmation before I consider a used purchase. My computer has an xp2000 and 512mb ddr ram so I think it can make use of a 9700p, though I guess it will be cpu limited. Anyway what card I get is still being researched, I am in a gathering information mode.
As far as the OS goes, I did not intend to have an OS debate here. I find 98se to be plenty stable for me, if it gets buggy I have ghost images with all my core applications and updates that I can restore in 20 minutes or so. The computers at my work are XP and are a lot more trouble, mainly because they're poorly maintained, but it also feels like XP picks up a lot more crap off the internet because it is the primary target. If someone knows performance or other significant reasons why I might want to pay $100 or more for XP to duplicate what 98se does for me I'm open to listening, but the fact that 98 is old does not by itself convince me.
