I bet that 0.027" will be easier to work with and still provide good heat transfer.
Keep in mind that I have a Northwood CPU, which helps A LOT since less hot air gets dumped onto the fins for the GPU. My 3.4 GHz Northwood hit 52°C ( well. bouncing between 51 and 52 ) on that test.
I haven't gotten around to making the bottom parts as I am still trying to find proper fine-thread screws to attach the pieces to the bottom. Once I find the screws, it should take no longer than 30 minutes to make the bottom sinks.
I was able to get to 455 on the core before it shut down. It looks like it is running OK at 450. Before I did the mod. it would shut down at around 440 and safe at 432.
I made the copper one the same size as the origional one by flipping the origional one up-side-down and etching the pattern on the copper. I made all the tongues ( the two top ones and the two bottom ones that need a screw hole ) that touch the GPU PCB about 0.25" longer than the traced pattern to allow for bending the 90° angles. You'll need to do the same thing with the four tongues that attach to the main heatsink. After getting the bends right, I just ground off the excess and drilled the holes. I used the inner part of the copper to make the extensions that will bend back over the place where the ram chips are. I also only made them as wide as the two chips so there would be more length for bending. The only one that will be a little short is the one on the right side since, on the flat sheet, it will touch the right side of the bottom ramsink.
Some tools that really came in handy are a small set of precision files. I got a six-file set from Home Depot awhile back which I used to work on the tongues. I got a block of wood and used a 1/4" wood carving tool to cut notches in the wood. I used the notches and a flat-head screwdriver to make the 90° bends on the tongues.

Not sure on that as this GPU used the same core ( R3xx ) as the 9800 series desktop GPUs.
