I can get this to happen consistently with my Unibody MBP in Vista x64.
1. Get 3DMark06
2. Run the test
3. Observe during the second test (flying fairies)
4. System will black screen at 47 seconds, EVERYTIME (right as they enter the tree bark).
Test it for yourself,

Would be good to have a consistant test that we can verify.
As far as other games, Left 4 Dead has crashed on me a few times.
OSX hasn't had any issues for me, with WoW or Flatout 2.
All of this ***** because I has no problems when my BootCamp was with XP 32bit...bah! I finished all of CoD:WaW on my MBP!
I have also done all of the updates listed here (
