it would be great if someone added a pre-compiled version for windows containing the opencl files and bin files for all the latest amd cards
p.s. i tried in so many ways to run my r9 290 (non x) on windows 8.1 following what i read here but for starters i'm a noob and the best result i got so far was seeing the hashrate go to 4.2mh/s but i wasn't getting any work from the pools and i was seeing HW errors, so i decided to roll back to my older drivers and wait for a revised or easier to run version for windows.
try this one ....
