This tool is great! Getting a better hashrate than ever with the version that I downloaded from cryptomining blog http://cryptomining-blog.com/3013-nicehash-control-tool-with-amd-radeon-280x-support/

Of course you'll want to update the Control tool to 1.0.4. Actually making a small amount of money now at nicehash. Up 'til now, this was just an expensive hobby! Thanks!
