I think I overdid the shim thingy on my first try, I stuck the largest coin here, 25 cents, under the gpu. Sure it applied lost of pressure on the pins but also flexed the logic board like crazy.
I always wanted the learn the heat gun reflow trick, looks now I'll have to. Maybe if I get it working in the end I'll cut a nice copper foil and place it over the GPU to help with the heat issue.
