The reason that bigadv gives such huge bonus points is because they're very complicated WUs. It's like having different size puzzles. You get more out of putting together a 2500 piece puzzle than a 100 piece puzzle, right?
So, it's a bit of a grey area, you are solving harder problems that are less likely to be done without your top end hardware, but you aren't necessarily contributing "more" than anyone else by doing them.
Sorry to stray from topic.
