Based on my previous experiences with Windows 2000 SP4 and Windows XP SP2 with NTP and WTS, I can assure you the performance you've obtained is the best you can hope.
With Win2k synced on a RS232 GPS I had an offset of + / - 5 ... 10 ms (far away from a FreeBSD system). Please note that on a heavy loaded system (Windows / Linux / any operating system) the performances degades rapidly (in the order of hundreds of milliseconds or in some cases more). We have in our NOC a server with 2 Xeon / 1.4 GHz / 4 GB RAM / 1,5TB HDD -with Linux - a heavy loaded machine. The offset is sometimes more than 400-500ms ! When there is a very low user activity the offset is 1-2 ms, synced with an internal Stratum 1 server on a gigabit network.
