CNET - An investigation by Apple shows some MacBook Pros may have faulty Nvidia graphics processors after all, despite Nvidia's earlier assurances to the contrary, the computer maker has announced.

I bought a Mac Book Pro 17" in May, and after installing Windows Boot Camp any of my favorite games (Supreme Commander) would drive GPU temps to 80+ C; on one occasion the keyboard became so hot (too hot to touch, really) I freaked, shut down the game, booted back into OSX and could not lot in - keyboard was constantly repeating. I had to shut down and let it cool off for an hour, after which it booted OSX fine.I've simply had to avoid playing any games at all, as the GPU simply runs too hot on this platform. I've read elsewhere that this issue is heat-related as well, and NVidia is releasing a driver update to address that:

I already use smbfancontrol but that only lets me adjust CPU fan speeds, not GPU that I can see.

I don't want a repair-if-broken, Apple, I want a recall and a replacement! For a $4K laptop, I expect better.
