I have a new, pretty loaded PB17 that's a little over a week old. I just ran xbench on it and was shocked that it scored in the 85-86 range. I know I need to optimize my HD with Disk Warrior or something after installing all of my software/transferring files, but it seems a little ridiculous for this machine to be scoring lower than older PBs I've seen with far less than what I have. Any ideas on fine tuning this thing for better performance? Thanks!
