The problem wasn't with WoW. It ended up being tracked down to the RAM that came with the machine being known to be bad: http://forum.thinkpads.com/viewtopic...afbf2e4d29cc6f
I don't crash anymore, but I still have massive problems with overheating due the poor ventilation system around the GPU. I normally run WoW at 110-115 C which is way too hot. This is with the fan set to max speed. More info at http://forum.thinkpads.com/viewtopic...=303069#303069
The best drivers that I could find for benchmarks and stability have been from Lenovo either via their update software or Windows Update. The other specialized/hacked drivers have always tested slower.
