Daytona is at least two or three years away from being emulated at full speed on a PC, probably more. A better bet might be the Dreamcast version, which is extremely faithful to the arcade.
Actually, a Dreamcast would make a good addition to any mame cab since it's basically a stripped down Naomi board. AFAIK it can be hooked up to an arcade monitor and arcade controls (via a controller hack) pretty easily.
