Again, it seems you are out of touch with current systems. Windows PC's are used all the time for recording and performance. The software and hardware work well.
You are asking about a soundcard for a PC with Midi so you are relying on a PC for performance. While the best piece of hardware is the performer, I'm not sure what it is you want.
Tell me specifically what your use will be and maybe I can help you with a solution that actually fits your needs.
