The answer to your question is no. You will not get that much of an increase in your score with only a few drivers running. To get a good score (6200+) in 3D Mark 2000 you will need the following:
-GEFORCE 2
-CAS2 Memory
-PIII or Atholon
-System tweaking
You could hit cnt,alt,del and not run your virus scan or other programs that are not needed.
