I was getting huge trouble profilling with my hd 5850 with the 3.4 version because for a weird reason the tool gave an error "Unsupported hardare" (while the doc state clearly that my card is officially supported). I have two 5850 and 3.4 wasn't usable. I have to step back to 3.3 to do my profiling but with huge capture the profiling always crash. When I saw 3.5 this morning I was very happy but THE LINKS ARE BROKEN! After the agrrement I get thi to work on boths: File "AMD_GPUPerfStudio220.127.116.11.zip" does not exist.
Same for the msi.
Not sure if you still need the links but the files on this site were working for me when I checked them: http://developer.amd.com/tools-and-sdks/graphics-development/gpu-perfstudio/
Looks like the issue may have been resolved since your original post.
