Mostly because the tommies scene renders out in 3 minutes 58 seconds on my athlon and 2 minutes 58 seconds on my p4 using the settings you suggested (1024 x 467 Final), which really isn't long enough and complex enough to gauge whether one system is better than another, which is kinduv the whole point, no offense, I just think we need a more complex scene here that really shows what the time differences are.
