First, tell me why you couldn't download the driver file from AMD? It's working well enough when I test it!
Are you using some really out of date browser? My own FireFox is up to version 27 now, and IE is still garbage.
Obviously, they have aimed their Beta toward newer cards (although I personally don't have a Radeon any newer than yours!)
Anyway, this custom modified one has worked for just about everyone who has tried it, but I will add a caution that at least one member spotted the download site trying to bundle in some unwanted software at the same time, so keep your eyes open:
