Since it looks like Apple is going back to nVidia with the exception of the Mac Pro I'm kind of concerned that the nVidia GPU's are going to be an issue. I've owned 4 nVidia powered computers over the years, all of them had hardware problems like crashing, BSOD and graphics corruption with the nVidia video card. On the other hand I've had 5 ATI/AMD powered computers (including all my Mac's) and never had an issue. And I know Apple dumped nVidia because they were having problems with the nVidia cards. So are these new nVidia based MBP's actually better or they the same old crap nVidia has been putting out for years? I'm just really worried I'll buy another nVidia lemon if I get either a Retina MBP or next gen iMac.
