I wouldn't advice you to use it, I've been looking for Extreme GPU Bruteforcer for months, because of the advertise, and to be honest, it was... a shit when I tried it out, of course this was months ago.
When you compare to oclHashCat it's really bad, the performance of both programs is similar, but Extreme GPU Bruterforcer won't give you the possibility to run at lower performance it will always run at maximum speed, while oclhashCat can run at lower speeds so your computer can crack and not be useless for hours, I've cracked at 200M/s (if I recall correctly) and the computer was running smoothly.
Of course there have been new versions for Extreme GPU Bruteforcer, so it might be better, I noticed they have a lot of new algorithms, might as well try it out.
And never mind CPU cracking, that's history, we're on GPU time.
All you need is a ATI HD or a nVidia 8000+. ( To support CUDA)
