The Apple store sent my MBP off after I demonstrated the strange graphics problems so many of us have noted (text tearing in Safari, flashing white blocks in Finder, iPhoto, etc). Anyway, it came back with this: The following services and/or replaement parts were used to service your product: 605-1452 PCBA,MLB,2.4GHZ-THERM,M87 Now I'm assuming MLB means main logic board and that means they replaced it. My other question is, since I have the now infamous GeForce 8600M GT video card, was that replaced as well? My understanding is that the graphics cards are soldered onto the board so that would mean yes, right? If so, does anyone know if the newer NVidia cards are ok? I'm trying to make myself feel better about this whole NVidia nightmare .
