I just got done re-building Bubbles after me main HD crapped out yesterday, and one of me final tests is always a benchmark run. I really do find them to be a great way for me to make sure I didn't miss any tweaks or forget anything in the re-build, and me fave is still 3dm2k1se. When I got done re-installing/tweaking I ran it and scored within 20 points of me pre-HD dying score.

(Oh, gratuitous
3dm2k1se compare URL 
)
But I'm starting to like 3dm2k3 too, it's just as consistant for me in scoring and now that I got the 9700 Pro it's actually pretty cool to watch too.
Bubbles' 3dm2003 score is just about exactly the same pre-rebuild & after rebuild too.
So what is the current consensus on 3dm2003? Does it blow or is it good at what it does?
