I got the card a few days ago, installed it and got 50k aquamarks and 3k 3dm05s.
The next day the scores dropped to 36k & 2.2k respectively.
So I did a new XP install and got back to 50k & 3k yesterday.
And now today its gone down to 37k & 2.2k again, and this is with only the essential processes running.
meh :/
Are you rebooting the machine between installing the drivers and running the BM tools ?
Im guessing not and that some part of the driver install is not working until after the reboot.
I think it was my usb tv dongle, installing the agp drivers after the tv ones seems to work :)
