I had the 9600 Pro and it was a great card, albeit it had all of its features enabled and the 9600SE is a crippled card.
You can get a 9600 Pro used on eBay for like $35-$40 (I know, I sold mine for $35 a couple weeks ago).
My 9600 Pro played Half-Life 2, WoW, Doom 3 decently.
Obviously they couldnt run at like 1024x768 at high res, but Doom 3 ran very well at 800x600 at medium, WoW ran well at 1280x1024 with some of the graphics intensive stuff turned down.
