Not benched this rig since i was on 32Bit XP a while back, however ive no 32Bit install now.  Anyone know of something that will actually allow me to benchmark this machine?

3DMark06 Basic Edition works fine on my fully updated XP64 install.

Not tried anything else. I assume the new version of 3DMark will work too.

All 3DMarks work for me.....

Actually, not too sure about 2000, but 2001 and on certainly does.
