Open Grapher.app in Utilities folder. Under the Examples menu there are 2D and 3D sections. Every time I chose a 3D one an additional window for it came up and view automatically rotates around them.
I think I had 10 Grapher windows open (some were repeats), and the MBP seemed to run them fine.
I left all Grapher windows running, and clicked to the desktop and started opening folders, doing Quicklook on everything, opening/minimizing/restoring windows, going to different programs. Any normal, everyday action that has animation effects that probably use the GPU to render.
After a minute or so of this my system froze. This isn't quite typical use but if it helps, replace Grapher with "export video from iMovie".
My MBP was already running hot after the Mountain Lion install, you might need to run it longer.

Hey ChanaiCh I'm having exactly the same issues you had. Hard freeze while browsing http://www.chromeexperiments.com/detail/cube/, also always when trying to export a video with iMovie, and also while playing Diablo 3. When I was trying to upgrade to ML my system froze so I took it to the Premium Reseller and they did a fresh install and everything seemed to run nice. (I live in Argentina, no Apple Stores over here, I bought this mac last month in NY, they dont sell MBPs over here just MBA). Today I installed Diablo 3 again and kept freezing, hopefuly Grapher.app does not freeze so I'm able to do my graphs for my studies. I believe I will need to have my logic board replaced unless Apple releases a magical update. Until I go again to the USA I won't be able to play any games or finish any iMovie proyect. I think I have one year warranty for this type of issue.
Sorry for my English.

Got my computer back Friday with new logic board, and so far the problem has not reappeared! Woo-hoo!
I put it through the same Grapher.app 3D example test as described above, the GPU temperature read as going to about 92°C. Ran the X-Plane demo, and the temperature peaked around 102°C like it did before, but again no system freeze despite switching to Finder while X-Plane was still running, and throwing different GPU tasks at it.

In the past, how long did you run the X-Plane demo (or grapher demo) before the computer locked?

Under Mountain Lion, the Grapher tests with all 3D examples running (in foreground; if the app is in background their animation stops) froze the system at the Genius Bar between 5 and 10 minutes, only because the system had cooled a bit between the initial install, reboot, and filling out initial user info. If I'd then reset the system and started the Grapher tests right away I'm sure it would've froze within 5 minutes.
Often the crash didn't happen in the program itself--it would happen shortly after quitting the program and doing something that invoked the GPU (like Quicklook or minimize animations).

I just installed smcFanControl and put it to full speed as a test. I was surprised how loud that was. I had thought it was a no-brainer that the fan was going full speed when the GPU went north of 95°C, and had been impressed at how quiet it was... now it seems the fan never went much above 3400 rpm the entire time I had this problem (3400 rpm is around when I start hearing it if I'm listening for it).
Maximum speed seems to be 6200 rpm and it's loud, there's no way I could've missed hearing it if it they'd been running at that speed. Even 4000rpm is audible over my air conditioning.

@ChanaiCh: How is your system running - still good? It's been 4+ months since your last post so I figure the logic board replacement solved your issue but wanted to verify...

my issues were solved with the MacBook Air and MacBook Pro Update 2.0.

Yes, still good, not a single freeze since the logic board was replaced. I've run X-Plane for tens of hours on it, it's even spiked past 100°C when I sometimes forgot to set fans to maximum first using smcfancontrol, and still fine.
Unlike senthor, I haven't applied the MBA and MBP Update 2.0 yet--it's still waiting in the App Store Updates section. I'll never know if that would have fixed the original problem on my MBP.
