Need to find openGL vid card..

Need a openGL vid card thats compatible with windows 98 and SiS 5597/5598 (need an updated driver aswell). I need it so i can play Medal Of Honor Allied Assault. Can someone please tell me what to download here. Thank you.
I would also like a new/updated driver that can handle openGL and is compatible with windows 98.

I appreciate it very much.
