the 23.1's were not any better than the 22.5's on my system, and seemed a little "loopie".  i didn't get any crashes, or anything overt, but i was glad when i rolled back to the 22.5's (gotta love WinXP's driver rollback).  anyone else have an odd feeling with those drivers?  images, even on the desktop, just seemed weird, but like i said, there weren't any actual artifacts or anything of the like.
