Hey guys, I have a 2007 SR MBP with the infamous 8600 GT card, and I've had to get my logic board replaced once already cause the GPU died. Lately, it's been showing signs of dying (artifacts in games, weird graphical glitches). Is there anything I can do to accelerate this process? I don't want to be stuck with this ticking time bomb of a graphics card, and my applecare runs out in September. I'd like to get a replacement laptop.
