Would you let me know *which* issues you are having with the card, or with
the time adjustment service from the driver package?

The advantage of PCI card is that programs can read the accurate time
directly from the card at any time, there are no interrupt latencies. So
the time adjustment service should keep the time as accurate as possible
under Windows. If that does not work then it may be due to a configuration
problem and it should not be too hard to solve this.

Take care, I'm biased ;-)
