Ok, I'm using these suckers also. Some points worth of mentioning
1) NOLF2 demo seems to run just fine (with 40.41 the performance was somehow strange)
2) UT2k3 upt result changed 150/59 --> 159/58
3) NOLF1 1.003 has strange graphical anomalies near text, vertical lines?
4) A strange flash occurs from time to time (horizontal) on different games
Also event viewer reveals some "NV" error that is probably related to some service that is not running, I have disabled pretty many services that are running by default on Win2000.
And the last, what is the Fast Writes problem? I have it enabled (by default) and I have noticed no problems so far.
Desire is irrelevant, I am a machine
