Ever since upgrading to the latest OS, my Mac Pro chugs along fine for several hours of use (or over an entire weekend just idling) then eventually starts to develop graphical glitches that coincide with serious unresponsiveness. Once this sets in, its usually only a matter of a few minutes before the system locks up entirely and must be restarted.
Here's what the screen looks like when things start to get weird:
I run a lot of programs at once -- many Adobe CS3 apps simultaneously, for example, along with iTunes, Word, Safari -- but it's unclear whether any of those is a common factor when the problems occur.
The console reports:

Crap, it's starting again now...
Any suggestions or thoughts?
