Eh? How do you define 'good' in a world of flawed technology? I wonder what it uses as a benchmark? When you have your score, what purpose does it serve? I mean - is this tool supposed to give you clues on what to do, in the event your computer produces a low score?
I'd be rather sceptical if I were you. The performance of meaningful applications like games, publishing tools and multimedia programs should provide you with some knowledge of how well the machine handles them. Installing more applications than you actually require to complete tasks with your computer could be classed as counter-productive.
