      I was talking more about the diff between VC8 and VC71.

Given that the difference in times is a factor of 57, I'm not convinced that
any greater precision is warranted.

It might be a good idea to launch the benchmark in a seperate thread,
then call something like:
double GetThreadTime(HANDLE t) {
  __int64 c, e, k, u;
  GetThreadTimes(t, (FILETIME*)&c, (FILETIME*)&e, (FILETIME*)&k,
(FILETIME*)&u);
return u/10000000.0; // user-mode time in seconds
}
to get a more precise time.
