So, the 320M in my 2010 MBP 13" died a few hours ago. It cannot render anything but basic 2D, this has been tried within Windows 7, XP and OSX with several applications and benchmarks. My MBP had a annoying slight vibration through the chassis when the fan was running even at base 2000RPM. After the graphics card died, this has now stopped. Also, I noticed that the fan was running far more often than on my old 2.26 GHz machine, but since iStat Pro doesn't display GPU temperature, I never bothered to check. If your MBP has the same vibration, consider returning it or getting it checked out. I honestly think Apple has a horrible track record, in regards to mobile GPU's, and if they can't provide me with a new laptop within 2 business days, I'm getting a PC of some kind(I have a exam Wednesday, and I need a computer for basic 3D rendering). Take care all.
