If you care for true OPL3 - get an YMF724-based PCI sound card. And please DO use VxD drivers - no card I know of exposes FM synthesis to DOS applications through WDM drivers.
If you do not care for OPL3 - get something like an SBLive or an Aureal Vortex2. If you don't really need/want EAX or A3D for Windows gaming, something simpler like a Creative/Ensoniq AudioPCI will do.
