    Still using a Dell 9400 here. The 7900GS failed before, and I did the oven bake which fixed it for a year. Its failed again, so I'm about to bake it one more time. Is it worth putting a copper shim on it. If so what one do I get?

    Well copper shims when done right, do help with heat dissipation not sure how much more it will help your 7900GS as compared to good thermal pads and AS5 paste.

    The 7900 card just runs too hot period, a good cooling pad and regular cleaning of the heat pipe assembly is your best bet.

    IF you find the card stays dead, you can also try the ATI 1400 card - there is a variant of the 1400 that was compatible in the 1705 laptop, and they work well enough.

    Good luck.

    There is no point in shimming the 7900GS? The heatsink already makes direct contact with the GPU die...

    Your shims isn't going to fix it you will have to have it fixed with someone that does GPU repair as your bake isn't really fixing the problem your having and eventually your GPU will die. As other mentioned the contacts are close enough and you don't need shims. But you need professional repair to fix the failure otherwise you will have to get a new GPU.
